Seventeen minutes for Mexican food I'd never eaten, on the word of Yelp strangers. Worth it. Sergio's is small and unbothered. You walk in and get "hola, joven" before the door shuts behind you. I'd ordered takeout. The woman at the register talked me out of it, which was the correct call and not mine to make. A booth was cleared before I could argue. Chips and salsa arrived without being asked for. I hadn't ordered a drink, because I was supposed to be leaving. Then: "¿Mijo, quieres una Coca?" Yes. Obviously yes. All of that happened before the food came out, which is the part worth writing down. Hospitality here isn't a service standard. It's just how the room works. Then the carne asada wet burrito. Chopped beef, great texture, and the serving was plenty. The sauce on top, beautiful red, great flavor, and perfect temperature. The salsa was actually spicy not your generic Mexican restaurant salsa. Cheap. Good. Nobody performing anything. I'll be back. Gracias otra vez. Son muy amables. read more

Excellent service and good food !! Loved everything . They were a little busy but the waitress handled everything with a smile and the owner came out a few times to say hello and make sure we were taken care of . We are ordering for a wedding so I'm excited the food tastes great! read more

Sergio's Mexican Restaurant - Mexican Near Me - Fontana, California

Tried out there menudo this morning and wow it was tasty! Satisfying my craving and the service was great!

The food was really good, the burritos were packed. The meat was flavorful and the beans were creamy. I ordered to go but the the lady at the register was so sweet and super helpful. She let me try the sauces for the wet burritos. It's pretty roomy inside a few TVs on the walls and light Mexican music playing in the background. read more

Nice restaurant on Foothill Blvd across street from Walmart in Fontana. Came on a Tuesday morning was seated quickly , server was friendly and quick getting our drink order and seating our party of 3. We were craving pozole and was delighted and they serve it everyday and not just the weekends. Delicious, seasoned well and soup was hot and not too spicy. My daughter got the Chiliquiles over medium eggs. She loved it. Was crispy with the tortillas and spackled up the yolk from the eggs. I got the upside down Tostada 10/10 Definitely worth a try if you're in the area. They have TV's all around for the sports fans to watch games as well They have plenty of room for larger groups. Good vibes read more

Excellent service, nicely decorated, & Authentic, yummy food at a reasonable price. We will definitely come back here again !

The carnitas and corn tortillas hecho a mano! Que rico! Everything Ive had is amazing!

We decided to try this place by our house since we love checking out new spots around our city, and let me just say... we're so glad we did! The mole was fire and honestly reminded me of my mom's homemade recipe. The enchiladas were also really good, full of flavor and satisfying. But let's talk about the horchata... it was DELISH! The atmosphere was chill, the service was great, and overall it was such a good experience. We'll definitely be coming back again read more

We have been here twice now and both times were great. I love the chips and salsa they serve you at the beginning. Salsa is a bit spicy, wish they had a milder option, but it keeps you on your toes... lol. The service was top notch, very friendly staff. They had so many options to choose from, that I wish they were closer to where I live so I could experience it all. Definitely a must try, their reviews and rating says it all and it's accurate and not fake. read more

Me and my family have been dining in here for a the past year let me tell you that the food is very authentic and delicious. Their customer service is amazing. They come and check on you. Ask you if you need more refills. Anything else that you need the coffee is always nice and hot. I highly recommend this place if you're looking for a great great customer service and delicious meal. They did a few catering events for me and my family and did not disappoint us or our guest amazing food amazing people, great environment and kid friendly. read more

Sergio's Mexican Restaurant - red chillaquiles - Mexican Near Me - Fontana, California

What I ordered: 1. Caldo de pollo (chicken soup) 2. Tacos dorado (hard shell tacos [chicken]) The food was the closest I've ever come to a home cooked meal. The soup was so hearty and flavorful I didn't need to put anything in it (but I did put lemon, cilantro, and onion because that's how I like it). The hard shell tacos are what drove me to come here initially after a recommendation from my father and they did not disappoint! The food is extremely presentable and it was hard to take a picture because I wanted to take a bit of it so bad! The chips and salsa are good also. They have a large selection of alcohol. The restaurant has the typical Mexican feel and they have lots of room for guests. They played mariachi music while I ate which is also one of my favorite genres to listen to. I will be bringing my family to this location. The service was great and I came during the week and I was 1 of 4 tables/ guests. Update on the restaurant after my third visit: I waited an hour to get my food, which is why I dropped my rating from 5 stars to 4 stars 100% recommend read more

What a great Yelp find on the way back to LA from Big Bear! Sergio's is a family owned and run business and this family knows how to cook! We were here for lunch and I got an Asada/carnitas burrito ($9.95) which came with beans, cheese, onion, tomato & cilantro and it was great - very tasty! Girlfriend got a shrimp/ asada burrito and it was the show stopper - their shrimp is amazing here. (He said they cook it in garlic butter but my girlfriend got hers w/o the garlic butter and it was still fantastic) Glad we stopped in and would definitely come back! read more

Sergio's Mexican Restaurant - Steak & shrimp and Pescado a la plancha - Mexican Near Me - Fontana, California

Came here to wait for an appt near by. Am pleasantly surprised. Had shrimp taco at recommendation of the waiter. Was the most flavorful shrimp I've ever had. The taco was definitely a do again (5/5). We also had a cheese enchilada- it was very very good. And we are enchilada snobs. The sauce was flavorful and delicious. The rice was perfect- it was unique in flavor from other places. But definitely homemade. Again a 5/5. Beans were also flavorful and delicious. Highly recommend this place. read more

Sergio's is the best! I have been a fan since they were in Glendora. Back then they were the only authentic Mexican food in town. When they left ( sadly) we were left with meh basic non authentic Mexican food. Wasn't the same since. Then, behold! We discovered they moved to Fontana!!!! What a wonderful surprise when it was discovered that Sergio's was owned and managed by the same family and the menu was just as we remembered . Delicious and authentic! I'm lucky to live closer now, my family now drives out from Glendora when they are craving the burritos, tacos, basically all of their menu because it's all delicious, great portions and service. We are so glad to re-discover them, and highly recommend!!! Let them know the family from Glendora sent you! :) read more

In my hungry rush to find a 4 star Mexican restaurant I landed her me at Sergio's. All I can really say is this place is truly filthy. It wasn't until I finished my combo chili relleno and beef enchilada (which passed as mediocre) that I noticed how badly this place needs a good clean. The floors and door mats were covered in what appeared to be days old droppings. When I went to the counter to pay my bill, I glanced over at the service area and could not help being horrified at the mess. The final straw was the filthy bathroom where I simply washed my hands good and headed out. Not sure if restaurant grades are a thing here, but clearly there was none posted. Please sanitize and clean up this restaurant ASAP! read more

The staff is really friendly and awesome. The food is delicious. Their salsa and chips are delicious and complimentary. My picky eaters aka 5 & 9 year old ate their beef hard shell tacos, chicken taquitos, rice and beans. My shrimp tacos and my husband's carne asada fajitas were delicious. We usually order take out but we dined in today and it was a great experience. The music was fun. We are all our food before I had a chance to take pictures. read more

Sergio's Mexican Restaurant - ENCHILLADAS, BOMB! BEANS, BOMB! - Mexican Near Me - Fontana, California

This place surprised me, I'm not gonna lie! From the outside appearance, I was unsure of what to think of this place. But as soon as I walked in, I thought that it was gonna be a solid place to eat. As soon as we walked in, we were greeted and seated at a location of our choosing. The gentlemen who helped us immediately wiped down our table and let us know that they'd be right with us. Immediately our waiter came up and the team brought us some complimentary chips and salsa and it was pretty good. Our waiter joked with us a little bit and established that he wasn't just another NPC/robot in the world which was nice and then we ordered our food. I got a combination plate of shrimp taco with the chili relleno and rice and beans. My mom got the taquitos with the chile relleno and rice beans. Let me say that this food was so good that I ate every last bite of mine and also ate some of my mom's left over chili relleno. Not only that, but I think that this place had the best chili relleno that I've ever had. It was the perfect balance of sauce, cheese, and pepper. I felt like I got the best of each item - which was surprising because most people treat chili relleno like it's not a big deal and they just slop a broken pepper with very little cheese and way too much sauce together and call it good. But at Sergio's, they made it with purpose and care. I really loved it. Their rice was fantastic too. Everything tasted truly authentic. I'm definitely gonna be coming back here to try more things. I recommend that everyone give this place a try. The moral of the story - don't judge a book by its cover, sometimes the perfect flavors are inside! read more

Came here for an early dinner and was our first time trying it. When we arrived, we were greeted by a gentleman and let us pick our table. We ordered the following: Pineapple Agua Fresca: 10/10 perfectly balanced and sweet. Red Enchilada: 6/10 sauce was more on the starchy side. Not my favorite. Shredded beef was good though. Crispy taco: 9/10 this would be a 10 if they added more cheese and used fresh grated cheese Chile relleno: 7/10 ours happened to be spicy (but I love spice) and the sauce was ok. I wasn't a huge fan of it. Beans: 10/10 BOMB, perfectly salted!!! Rice: 5/10 on the dry bland side. I will opt for double beans next time. Also, they offer Menudo EVERY DAY!!! I was able to sample the broth and it was good. Solid 7.5/8 out 10! Definitely will be back to try it! Also, chips and salsa were delicious! Our server was awesome and very nice!!! We will be back and try other things. read more

Let me start of by saying the services is 10/10 I placed an ordered thru grub hub and my asada burrito did not make it with my order. I called right away, the man who answered said it was not a problem and they would make it for me then have someone bring it to me. Usually when something is left of of a delivery the restaurant makes you go pick it up or offers other options. So I am extremely satisfied with the customer service because the restaurant hand delivered my burrito. Now my fiancé is the one who wanted the Asada burrito and he has tried many in the area but he said this one was literally his favorite. We had not found a burrito he liked until now! We will be definitely coming back because I need to try it myself lol. I ordered two molitas one with grilled chicken and one of carnitas and man those were delicious! My favorite was definitely the carnitas but they both were flavorful and made with homemade corn tortillas! The horchata was extremely good probably my favorite in the area. Last but not least the Chile verde, now I'm very picky when it comes to Chile verde because I make it myself and I tend to like it a bit spicy. I seen the reviews for it and decided to try it. Now it's not my favorite, they definitely make it different. I probably would not order it again but everything else we had was super delicious so I had to give this place 5 stars! read more
