I finally came here twice in about a month's period of time with the same friend. Once before and once after the Ontario Reign hockey games. The service both times was very good from the seating hostesses to the waitresses, as well as others that ran the food out to us. It is a really clean restaurant inside and out front, including the restrooms. Plenty of parking around, but gets full close by quickly when the Reign are playing. The first time I remember being under strict diet rules, so I was only able to order a chicken Cesar salad. It had a very good presentation and they cooked the chicken well and I was given a good amount of dressing. On the second visit I ordered the happy hour Eureka Burger and fries, which was about $13. Great price for a great burger made medium patty my way and awesome French fries!!! My friend and I love this place and we will definitely be back. Highly recommend!!! Come early or really late on Toyota Arena event days!!! read more

4+ pretty big chain at this point that has a really good spirits selection. I've had their burger and some food at another location a long time ago, but on this particular visit, I only came in for a drink. My buddy and I sat at the bar pretty much right away. We were waiting at the traffic because we had just gotten out of the Ontario Reign game across the street. The vibe here was pretty lively. It was pretty busy on a weekday evening. I typically order straight up whiskey at places like this, but I saw a cocktail on the menu that looked fun and interesting. It was definitely a fun drink with some performance aspects to it. This place is a great option for food and drinks, especially right by the arena. read more

This place is conveniently located adjacent to the Arena on the bottom floor of the Element Hotel... not connected though. I LOVE the Eureka in Claremont (near my home) and I thought I would check this one out. It was a cold and windy day and unfortunately, as people came in the doors stayed open and we were freezing. Service was better once we told our server that I was in the food industry - before then it was just meh. Clean restaurant with sorta dark interiors but a nice spot to meet friends and have a beverage or watch a game. Respectfully Reviewed. read more

First time trying this spot and pleasantly surprised. It's tucked across from the Toyota Arena. You might miss it if not using GPS. They had great menu items for adults and kids without overwhelming you. Mariah was an excellent server and the accompanying manager, Cesar came and greeted us. The ambiance was date-night worthy and vibe was chill. Will definitely be back without the kiddos;) read more

Eureka! is one of my favorite spots to come grab a burger and enjoy a cocktail. Before finding the Ontario location, I used to frequent the Claremont one, but that's going to change! To start, the service here is excellent. Our server, Trinity was very attentive and did a great job! There also wasn't a wait for us, but we also arrived a few minutes after they opened. The atmosphere on the inside is really nice! It feels more upscale but has a chill vibe at the same time. The food here was also excellent. Our table shared the mac and cheese balls and the truffle fries, you really can't go wrong with either! We also had burgers which were cooked perfectly! If you enjoy goat cheese, the Fresno fig burger is a must. Overall, this was truly a great experience, I can't wait to come back and enjoy another burger! read more

Environment was good. Food was good. Service was good. Pretty yummy food as well nice

Stopped by here on a road trip mainly because it was one of the few restaurants that was open late. It's located next to a hotel. There's plenty of parking behind the restaurant shared with the hotel I believe. It wasn't too busy late at night and the service was prompt. It had a modern bar like feel to it but it was quite chilly inside. Not sure if it's because we were just seated under the AC. The food was typical bar food and portions were generous. We left feeling satisfied and will probably keep an eye out for other Eureka! to try if we need a quick late night eat :) read more

My amazing daughter n law was in town and we decided to meet for dinner in Ontario. She chose Eureka and boy did she pick a winner..(she is also a YELPER) The food was delicious. We started with the Mac n cheese balls as our appetizer. Really good. My daughter n law had the wings, her mom had fish tacos and I had the cowboy burger and truffle fries... so so good... Our server was great (so sorry I forgot her name) she checked on us regularly and always had a smile. The ambiance is a bar type setting with TV's indoor seating and outdoor seating. We enjoyed the outdoor patio and it capped our evening off perfect. I can't wait to bring the hubby back. read more

I've been a patron of Eureka for a long time. Back when Claremont was one of two locations... because the IE had really any other restaurant like Eureka. The gourmet burger boom was born, and an oasis in the desert of the IE was this place. I definitely am not as faithful as I used to be, but when my wife and I have a rare few hours without the kids to hang out on a Saturday night, I realize there's a Eureka nearby, the location I'm reviewing now. I swear I was at the Claremont location a little less than a year ago and thought, wow, the prices are still pretty solid in this new era of eating out... both food and drink. WRONG. I don't know if it's just because this location is right next to Toyota Arena, but the prices are funny on a Buffalo Trace sour. $17.50... it's like I'm at some dumb old school steakhouse. At least they make the sour well here? Uncharted Forests was a banger of a cocktail. This was their saving grace. It was nice to see some really nice creativity in a cocktail when this chain is getting bigger and more watered down. The salad changes were bad. The rib tips getting axed from the menu is still unforgivable. They eliminate their most iconic trademark appetizer... just because? Every server I talk to when I come back, they all say the same thing. The faithful patrons all bemoan this dumb decision. When we first walked in, the two girls greeting/seating looked almost perturbed that we had interrupted the conversation. I had to sit there for a good few seconds before they looked at us and then another couple of seconds before I got tired of waiting for a decent "hello" or "good evening" and just said, "there's two of us." One of these girls while we were dining was sweeping up around the tables, sticking the broom under the table and around a patron's feet while they were still eating. It was weird. What can you expect when the place keeps expanding the chain? Watered down. I guess if you're in a pinch, they do make better cocktails than most other places around. If you're gonna be overcharged for a sour, at least it's pretty good. Oh, and they did improve the cherries. For a minute there, they stopped using lucrado charries because they wanted to go "all American." Looks like they've come to their senses and brought back the luxardos. read more

Grabbed a quick bite before picking up my target order, Taylor the bartender served me and I gotta say he's good at what he does! Not just the way he served me but the way he took care of everyone in the restaurant, he even acknowledged people waiting at the front. Appreciate it! read more

I hadn't been here in 5 years but I stopped by and tried the steak nachos, boneless wings, fries and the Eureka Burger. The steak nachos had your average decent steak, glazed with some sauces, what looked to be black beans as well. The nachos were decent, nothing to ride home about. Their boneless wings were also decent, Wingstop quality. The burger was the typical burger you get at these restaurants that charge you $19. Meat was pretty tender, ingredients tasted pretty fresh, overall not too bad. The fries were probably the better part of everything, they got a decent amount of seasoning to them, along with the crispness. Steak Nachos: 6.9 Boneless Wings: 6.8 Burger: 7.2 Fries: 7:8 read more

Eureka! - Eureka American - Burgers Near Me - Ontario, California

I used to love going here for food and drinks but my recent visit was very disappointing. My husband and I usually get the wings and this time around they were very small, about bite sized. We got my daughter a quesadilla from the kids menu and it states it comes with a side unless we want to upgrade for a different side not listed there for $3 more. I ordered her fruit which was listed on there and they still charged us $3. The drinks were also underwhelming, my go-to is the spa day margarita but it didn't have the foam it usually comes with and didn't taste the same either. The restaurant wasn't busy but the service was very slow and our food was cold. When we ordered a second round of drinks it took about 20 minutes to receive them and once I got my drink I noticed the glass was broken. This was my first Mother's Day dinner and I was very upset about how everything went down, especially because we have been coming here for years. We've had previous issues dining here such as cleanliness and we gave it another chance, but due to our recent visit I don't think we will be returning here. Unfortunately the food/drink quality and service has declined. read more

Really liked this location. It's a lot bigger than the other one I went to, only downside I guess is parking is weird because of where it's physically located. Food is consistent w other location. Service was very fast. Ambiance is also nice, dark lighting inside. read more

Eureka! - Wild child and mango beer - Burgers Near Me - Ontario, California

We came to Eureka! for a birthday and had such a great time! The staff brought out candles with the desserts we ordered and sang, which made it feel really special. The place was super clean with fast table turnover -- empty one minute, full the next. The star of the menu though? The honey cinnamon sweet potato fries. Ordered seconds even. Perfectly crispy outside, soft inside, with just the right touch of sweetness. I'd come back just for those! The only downside was finding the place since it's tucked inside the Element Hotel and not well marked -- signage would help a lot. Overall, once you're inside, it's absolutely worth it. You can tell "The A team" helped with service so it wasn't just one person visiting our table. They made sure everything was on point and you get everything you need right away. Great food, fun vibe, and an awesome birthday experience! read more

Eureka! - Burgers Near Me - Ontario, California

I was seated right away. I ordered Korean Beef Frachos (Nachos with French Fries instead of chips). They were very good. Maybe a little bit expensive. The waiters and waitresses were very nice. The music was a little loud but good. Nice decor. read more

The ambience and vibe in this place is immaculate. I really enjoy going here. I love it. Super low-key dark and intimate. It's a great hangout spot without being weird. Elegant and elevated and casual at the same time. The food is delicious and the flavors are intricate and fresh. Everything's a little bit different than usual so you don't get bored with the food. I went here with a group of four friends, five in total, and we had a nice time. The food is yummy :) read more

Eureka! - My friend took this of her whiskey sour. She liked it :) Brussels sprouts and Mac n cheese balls - Burgers Near Me - Ontario, California

I do not recommend, have been here twice, did not like either of the meals I tried, and neither did any of my friends. Also, the drinks are ridiculously priced. There is an option on the menu for a "pitcher" of one of their cocktails and my table ordered it to share! It filled maybe 4 SMALL cups. Just isn't worth it in my opinion. The atmosphere is cool though. Service is lackluster. read more

*** BE AWARE *** If you are turning right from Ontario Center onto Via Piemonte: it is a VERY wide turn onto a very narrow street! I was far from the first person to scrape the entire passenger side along the curb. The whole curb is black. (This has nothing to do with my review.) It's a small place that is OPPRESSIVELY LOUD. Almost every surface is hard, there is no sound abatement, and the music is too loud. I guess it's fine if you don't want to talk to anyone else in your party. It's easier to hear outside, but it was 90 degrees on the day we visited. We were there for happy hour. PLEASE NOTE: only 4-5 beers are on happy hour. Hubby ordered a beer taster and water with lemon, I ordered iced tea without lemon and with sweetener. The water and tea came (lemon was backwards) and sweetener options were sugar in the raw or Splenda. I've never seen anyone actually put SITR into an iced tea - it doesn't melt. No straw to stir it in with, anyway. I asked for one and it was paper. We weren't off to a good start. Taster arrived, and hubby ordered a beer (full price, oops) and 2 appetizers. Food was delivered by two runners, not our server. Brussels sprouts were good, and mac and cheese balls were well cooked but in desperate need of salt. (The ONLY thing I add salt to in restaurants are eggs.) Server finally came back by when we were done with everything, 2 minutes before happy hour was over. At that point, I just asked for the check. The food is probably good (everything on other tables looked good) but almost every appetizer has chilis in it. (I'm not a fan.) Most salads have no protein. Adding puts the price over $20 each. If we were in the area on a cooler day, we might give it another try, but I won't go out of my way. read more

My fiancé took me out for a belated birthday dinner after work. It happened to be Steal The Glass night which is every other Wednesday. They were giving out Brewery X glasses. The ambiance is dark and cozy. Great place to grab some drinks or have a date night. COCKTAIL/BEER: *Orange Wheat Beer - Citrusy and refreshing. *Wild Child Cocktail - Loved the watermelon and mint combo. It was super refreshing. The habanero salt rim gave the drink a kick without being too spicy. FOOD: *Fish and Chips - The fish was hot and crispy. I appreciate that there wasn't too much batter. *Fresno Fig Burger w/ Truffle Fries - Solid burger. I liked the fig marmalade. Also, can't go wrong with their truffle fries. Overall, the food was good. Our waitress was so nice. She even gave me ice cream at the end to celebrate! read more

I was in the area and decided to try this restaurant as it seemed quite packed. It's located across the street from a convention center/hotel so parking is a little bit all over the place... I ordered 3 items, nachos, salmon and cheese fries. The nachos were very bad, looked like they were just thrown together in 20 seconds with no effort and the cheese on them felt and looked like plastic, and the "toppings" on the nachos were just not anywhere near enough to cover much. Truffle fries were cold, and the grated cheese on them literally would come off with the fry like it was plastic cheese. And the salmon...very salty and practically uneatable, mashed potatoes tasted like baby food. My friends got two drinks and said they were both very watered down. Lastly, I kind of liked the interior vibe and ambiance of the place, however there was a group of people who walked in and sat right behind us, about 7-9 people. Unbelievably loud and very obnoxious and talking loud the whole time. I can understand guests being annoying but what shocked me was that no staff members felt like this was disrupting other guests, any professional establishment would tell these people to calm down and stop being so loud. Overall, a very disappointing experience considering a relatively busy restaurant, food was awful, only positive was that our food came out quick...which now that I see how bad it was, maybe wasn't so good. My advice...don't bother. read more

Can I leave zero stars? I called this location on Friday asking to make a reservation for my husband's birthday dinner for 9 people at 5:30. We had family driving almost an hour to meet us there. I was told by the young guy that they don't take same day reservations and parties that big need to be cleared by a manager. Weird. Anyway we show up at 5:30 only to be told they just seated people in the only area that could accommodate us. There were other open tables for couples so why wouldn't they have sat them there leaving the space open for us knowing we were coming at the time?! He said we could sit outside (it was over 100 degrees), sit on some couches with a coffee table set up or else wait an hour. I couldn't believe they couldn't, or simply wouldn't, plan for a large party for a special occasion. The young guys at the front didn't seem to care to help us at all. We ended up going to a different restaurant in the area and spent $300 there. Such a shame they didn't care to service a larger party and because of the poor service we would never come here again. read more

This is the perfect place to stop in for a bite before an Ontario Reign game (or any event at Toyota Center). The place is HUGE and has such a fun, vibrant atmosphere. Perfect before a hockey game! You can come here in your own or with a large group, and you'll be fine. Elysia was our server, and what a huge ray of sunshine she is! So incredibly sweet and took such great care of us. My friend had the double smash burger, and I had the pulled pork sandwich, both of which were EXCELLENT. It didn't matter that the place was absolutely packed before the Reign game ... service all around from when we were greeted at the entrance, throughout our meal, and when left was outstanding. This would be the perfect place to go for Sunday/Monday football or to watch any sports. Just an all around fun place. I'll be coming here before every Reign game! read more

First time here with a group reservation for 20 on a Thursday night at 8:30pm. Bastards gave away the reservation to another party and said the person taking the reservation A MONTH AGO didn't know about the reservation. 1 hour later we got water. 1 hour thirty minutes later they took the order. Hostess was rude as hell. Waitresses acted like she wanted to go home and not work. Never coming back, first time impression killed it. Oh the place is nice, everything else sucked. If you don't care to eat and sit in a noisy bar atmosphere, this dump is for you. Go to the Claremont one!!!! Stay away. Got my burger at 10:17pm. Wow!! read more

The service is amazing, the drinks are great, and the vibe was moody and brutalist. Loved it.

My eldest daughter and I had previously dined at Eureka! Claremont. We loved it so much, we had to come check out Eureka! Ontario. We came here for early dinner. It's located within the Element by Wyndham Hotel. It's diagonal from the Toyota Arena. Cool! Funny, we actually missed the entrance of the restaurant. Anyway, we were greeted right away and seated shortly afterwards. Ambiance was on the darker side, but kind of romantic with the dim lighting. There are inside and outside patio seatings. Check-in staff was super friendly. Our server was amazing and very helpful with recommendations. He checked back with us regularly to ensure all is good. Another gentleman asked if everything was okay... he may have been the GM not sure though. Thank you for the exceptional service! We came here primarily for the crispy glazed brussel sprouts so we got 2 orders LOL. Unfortunately, it didn't taste as good as the one we ate at the Claremont location. The brussel sprouts were not tender... quite crunchy and firm. The orange chile glaze was not as sweet. It just had a whole different texture and taste. Slightly disappointed because this was the original reason why we came here. We also got the chicken wings with half firecracker and half Eureka! bourbon-smoked dry rub. Well, it wasn't exactly half because it only comes in 7 count which I don't understand. If it's a shareable, it should be an even number so it's fair for all parties. Anyhoo, now these were amazingly delicious wings! I would get these two flavors again. I would have to get 2 orders to get to an even number next time LOL. Lastly, we got the seared Ahi tuna salad. This was good, too. Nice amount of salad and thick chunks of Ahi tuna. Somehow I lost the photos I took for this salad. I'll post the photos the next time we get it again. All in all, a wonderful dining experience with great ambiance and delicious foods. We may be back again if not for the brussel sprouts, the wings for sure. Thank you Eureka! Ontario! read more

I have always been curious about this place and today I decided to finally try. All I can say was that I was impressed. First the service was great. I had Kalis as my bartender and he was friendly. He provided amazing customer service and gave some great recommendations. He continued to check up on me even when it started to get busier. He recommended some of the food I got. So for the drinks they have a great beer selection. Today I tried the Bottle Logic's Huckleberry Blonde and it was delicious and light. Kalis recommended the double smash burger and the burger did not disappoint. I had also tried the bourbon barrel cake. Everything I had was delicious. The ambiance at the bar was amazing and all good vibes. They had some really good tunes playing. I give this spot a 5 and I will be back. read more

Eureka! - Fresno Fig Hamburger - Burgers Near Me - Ontario, California

We drove over an hour specifically to try this restaurant and were excited to finally visit. When we arrived, there was no hostess at the front, so after waiting briefly, we seated ourselves. The restaurant only had a couple of customers at the time, so we didn't think it would be an issue. Shortly after sitting down, the bartender approached us and appeared visibly frustrated. Instead of politely explaining their seating policy, she spoke to my wife and me in a way that felt unnecessarily rude and disrespectful, telling us that we needed to wait to be seated next time. We completely understand that every restaurant has its own procedures, and we would have gladly moved or waited if asked respectfully. What disappointed us was not the policy itself, but the manner in which we were treated. First impressions matter, and as customers who made a special trip to dine there, we left feeling unwelcome and unappreciated. Rather than continue our visit, we chose to leave and spend our money elsewhere. We hope management takes this feedback seriously, as a little courtesy and hospitality can make all the difference in a customer's experience read more

We ordered the Fish and chips and it did not disappoint. That is my go to favorite The place is hard to find since it's inside a hotel.

Fan since day one! Literally...... Everything I've eaten here has always been good. They serve these Mac & Cheese balls that are just scrumptious. The cocktails on point. The espresso martini a favorite because they make a really good one. Every server here always has a smile. It's a chic looking spot with a nice vibe. I bumped into Crystal Waters at the bar, last night after the Freestyle Concert at Toyota Arena. #iykyk She couldn't get a table, so she sat at the bar for a quick meal. I went over to say hi; she asked me: "do you want to take a picture? " I replied: "I'm supposed to ask you" and she laughed and gave me a hug. The highlight of my Saturday night! All of it at Eureka! Happy Spring everyone! read more

Came here for happy hour. It was bit hard to find as it is attached to the hotel called Element by Westin. Food is fresh, hot. Some pieces of the ahi tuna were a little stale. The crispy wings were piping hot and crispy indeed. Double smash burger was well seasoned. Service was prompt and nice. Ambience is cool with music. Will come Back! read more
