Had lunch here with the family since we were craving "burgers". Wife and I had the veggie burgers, my daughter had the hot dogs and we shared fries and onion rings. The food was fresh and well cooked, everyone enjoyed their food. The lady who took our order and made our food was nice and friendly. The place was clean and very diner like. The one complaint was from my daughter about the ice machine being loud, but that could also have been because we were the only ones in the restaurant. read more

Yesterday, the crew from Bob's Burgers decided to check out the local competition. We headed over to The Red Onion in Concord. We were welcomed by our fellow burger flippers. The burgers were delicious, and the service was terrific! The onion rings were so good, too! Seven of us really enjoyed our burgers; we were chowing down within ten minutes of ordering. This is an old-school diner with a great vibe. I'm adding this spot to my regular rotation. Let's show this hamburger joint some love! They made great burgers and took wonderful care of this crazy crew!

A decent spot for some diner grub, the staff is always friendly and the burger and fries are generous and fairly priced. They have some other food options but this is our go to spot for a quick local burger made to order. read more

Agree with most of the reviews on here. Very clean nice atmosphere with friendly staff. At almost 11 bucks for a hamburger with tax I'm sorry but it's just not worth it The meat tasted completely unseasoned. Better burger just down the street at a better price point at best burger read more

Yummy large burgers, fries and pineapple shake with an old school diner vibe. Great service!

Another well deserved 5 star review update for one of my absolute favorite Bay Area burger spots! I love this place with all of my damn heart. The Red Onion is my favorite burger spot in CoCo county, period! I can talk all damn day about how delicious their burgers are, but another big reason why I've consistently come here for years is because of the excellent service. Silvia and her family are some of the kindest and most hardworking people in the game. I have so much respect for them and their business. I stopped by to pick up dinner this past week, and I was pleasantly surprised to see Silvia (the owner) working there that night. She usually works at the El Cerrito location now, so it was nice to see and chat with her. Her daughter was there too and she's always been super pleasant. They always remember me even if it's been months since I've come in. There have been times when I've come in on my cheat days when I'm dieting, and we always talk about our weight loss journeys and dieting. I feel like this family is an old friend at this point. It makes me so happy to see them when I come in. What more can I say about their burgers that I haven't already said time and time again? They're just friggin' scrumptious. Huge, meaty, juicy, and fresh. And every single damn time too. This is one of the only spots that I'd prefer over an In N Out burger. And if you're a diehard In N Out fan like myself, then you know that's really saying a lot. The consistency is just bananas. They've got it down to a science. Burgers and fries are just too damn good here. Always grateful to have this wonderful burger spot around, and I'm so glad that they didn't fall victim to COVID. And, now I've just worked myself up a craving for one of their burgers. Guess I better get up and order me one! Mmmmm :). read more

My son and I ate here today as recent transplants to Concord looking for a good burger. I can't believe our experience! This was the CLEANEST restaurant I have ever been in. The fryers, grill, entire back kitchen area that is completely visible, sparkling clean. I couldn't believe it and neither could my son who has been a GM in restaurants. The lovely lady that helped us answered our questions happily and took.our special requests in stride. When we were done we found out she was the owner. Completely delightful lady! But I digress. I ordered a cheeseburger, well done, fries and a coke. My son ordered a double cheeseburger add avocado and extra bacon and a BLT with avocado and extra bacon and onion rings. My son and I unanimously agreed this was the best burger we have had since we can't even remember. I am picky. Very picky. This was the BEST burger I have had in years! My son was sitting at the table talking about what he is going to order the next time we go and what he thinks his dad and brother would order. I can't stress enough how good the service and food and cleanliness was here. The lovely woman that helped us is Sylvia and she turned out to be the owner. I think we are going back tomorrow that's how good it was. I rarely feel compelled to write a review but this place earned a review from me. Get a burger! You won't be sorry! read more

FULL DISCLOSURE: Only reason this doesn't get a 5 star is because the business hours are inaccurate and not updated. Other than that the food is amazing! Essentially the place is a high quality food version of nations. Juicy burgers, big in size and amazing French fries. Very old school feel but it's comforting. Reasonably priced and overall a great place to eat.. Please fix your hours!!! *picture for reference* read more

I grew up on Red Onion Burgers and ate at the original one in Pinole. I moved and saw one in El Cerrito that was closer to home and went there several. Recently, I found this Red Onion in Concord. I swung by for lunch and got a cheeseburger and an order of fries. My buddy went for a cheeseburger and onion rings. The burger comes on a nice fresh, soft and chewy bun with a fresh not frozen hamburger patty, lettuce, tomatoes, red onions, American cheese, miracle whip and mustard. It is a very fresh and tasty burger. I think they put less produce and the patty is a bit smaller than the Red a Onion in El Cerrito or Pinole but still a very good burger. The fries were hot, fresh and crunchy. Sadly the onion rings seem to have a heavier older oil taste but crunchy. Red Onion is on my go to burger list, it looks OG but it is very clean, comfortable setting and the people are very nice. If you are in Concord, stop by for a fresh tasty burger and nicely cooked fries. I'll be going again. read more

Ordered a Cheeseburger ($7.50) with bacon ($1.85) and a side of Onion Rings ($4.25) with an ice tea ($2.25). Total with tax $17.97. For a cheap eats place, kinda pricey, but the size and quality were good. I really like the amount of seasoning they put on the burger. All the toppings (head lettuce, red onion, tomatoes) were very fresh. The bun was a good size and held everything together. Also came with mustard and mayo. The bacon was crispy but not overcooked. I liked the onion rings. They were not fresh, battered and frozen but still came out good. Not greasy and enough for 2 people. On the down side, the Ranch was not that great, so ate the onion rings with ketchup. Glad I didn't pay of the Ranch. Would I come back, maybe if I'm in the area but I would not travel out of my way. read more

Thoroughly mediocre. The salmon burger we ordered arrived with a patty that seemed to contain some kind of fish but was certainly not pink (as salmon is) and had mysterious other stuff in it. Cheese on the burger was disgusting, shake was bad and didn't match our order (ordered chocolate malt, got a plain vanilla shake), fries were pretty good though. Attached picture of the ostensible salmon patty, which doesn't look or taste like salmon. read more

The Red Onion - """salmon""" patty - American Near Me - Concord, California

Having a flat tire repaired and was starving . I saw this place walking down the road. Nothing much to see from the outside but I was hungry so I wondered in. Wow. Place was so clean and nice inside. This place has an old school counter to eat at and watch them cook your food. Hamburger was perfect . Fries were cooked perfectly. The person serving me and cooking for me was also extremely nice. But I have to say one of the cleanest mom and pop restaurants I've ever been in. Next time I'm back in Concord I will having my burger here! read more

This place is a hidden gem and is underrated. My daughter had a track meet a mile away so we stopped by this place since we didn't want to wait in long lines at In n Out. First, there was parking. Second, I was so impressed by the food! We had cheeseburgers and they were moist but cooked just right. We also ordered the chili cheese fries which were delicious. The price is decent for what you get. Ambience was average, not a fancy spot but great for kids and worth the pit stop! read more

Food was awesome. Nice crispy fries, not greasy, decent flavor. Burger was a good size, loved the toasted bun, high quality fixings on the burger. Good potent fresh red onion! Hot dog was delicious plain. read more

Great cheeseburger and BLT. Restaurant was spotless and employees were very nice. Its a must try!!

Back for a lil family meal and this place hit the spot! Double cheeseburger is my got to. Feeds you for most of the day. The onion rings and fries again cooked to perfection. Fries are hot crispy and slightly fluffy on the inside. The rings are lightly crispy but with the perfect crunch and texture on the inside onions that they just melt in your mouth. Family loved the chili dog and the grilling split of the dog. Our go to burger spot. Going to try the grilled ham and cheese next. read more

Good place! The food is at a fair price, it's pretty good. The meat on their cheese burgers could use some more seasoning, there's not a huge flavor profile to them. You can tell they use fresh ingredients like the lettuce, onions, etc. the service was pretty good, the staff is super friendly. It took about 10 mins to get my order 2 burgers and fries, which isn't too bad. Maybe not the best place if you are in a rush though. read more

Just basic, good grub. Not too fancy, just cheeseburgers like dad used to make on the patio on Sunday afternoon. Highly recommended.

Horrible. Was charged $3 for a canned soda. The chicken sandwich was under cooked and not edible. French fries were good. Overpriced and gross. The ranch was given to me in a ketchup bottle and the top came off and poured all over my food. Awful experience for a $25 lunch. Chicken sandwich, french fries and a can soda. Overpriced and gross. Will not go here again. The red onions in Richmond and el sobrante are really good. This one is disappointing for sure. read more

A bit expensive but clean and fresh. We enjoyed the food. Onion rings were okay. The shakes were good.

The food is pretty good, better than fast food that's forsure. The only downside like others are saying is the price point. It's very expensive now and the quality hasn't changed. I can get a full meal at in n out. They do give you a lot of Frieda and the burgers are pretty good, but over $8 a cheeseburger is a lot. I also don't like how they keep the lettuce on the grill while your meat cooks with Mayo. It leave your burger with hot Mayo and wilted lettuce. read more

Service - outstanding service. Super friendly, like going over to a friends house. Food - delicious burger. Good size. Definitely leaves you satisfied. The tough choice is whether to get fried or rings vs two burger. Yes my friends the struggle is real Price - reasonable. Good budget val Parking - located in strip mall there is usually ample parking read more

Solid locally owned business that lives up to its name The Red Onion. We stopped by after craving burgers and wanting to try a new place. We were pleasantly surprised! Their burgers are fresh and cooked to order. Though note that they're pretty big patties. I got the double cheeseburger and wished I got the single. Comes with mayo, ketchup, lettuce, tomato and RED ONIONS. Bun is toasted but still soft. Burgers are juicy an flavorful. Onion rings were nice and crispy though fried from frozen. I'm usually more a fries person but they lacked flavor. The fries and no pickles in the burger kept it from a 5 star review. Milkshake machine was down due to COVID so I hope to try that next time. It was take out only but the interior had some vintage Coke decorations. read more

The Red Onion - Double cheese burger - portions are HUGE - American Near Me - Concord, California

I wanted to try something new and since I'm out in this area every two weeks for work I decided to try some local cuisine with my buddy. We came to this location about 40 minutes before they closed, but the lady at the counter never rushed us and made me feel very welcomed. I ordered a cheeseburger, onion rings and a coke. Unfortunately, they were out of normal buns and only had wheat buns, but it wasn't a huge deal and I'm glad the lady told us. We waited about 8 minutes to get our food and man I gotta say this was some solid food. The onion rings were delicious and were even better dipped in ranch. The burger was huge! Total amount was about $13 bucks for everything, but it was worth every dollar. I know I will definitely be back at this location soon again to try more items off the menu. read more

The Red Onion is soo good, it's one of my top burger places. I've been coming here since I found out about it. The burgers are delicious, and they're consistent every time. The workers are friendly and they definitely put some love in the food. I get the same thing every time, a cheeseburger with bacon and a side of chili cheese fries. The actual restaurant is a clean little old-school place which is a nice experience. If you're passing through, I definitely recommend going here. And if you're a local, you're gonna love coming back read more

THIS PLACE HAS THE BEST CHEESEBURGER YOU'RE EVER GOING TO BITE INTO !! The burgers are so delicious and juicy. I discovered this place just two weeks ago and I've already been here four times. I'm not joking when I say it's the best burger I've ever had. The burger is really big I could honestly eat half and be okay but it's so good I go for the food coma, and it's worth it every time. The chili cheese fries are also the bomb definitely recommend this restaurant 10/10. I forgot to mention but you can see the cook cooking right behind the counter on the grill making your food! This place will not disappoint I PROMISE !! read more

I have ALWAYS LOVED THE RED ONION. This store is just great. The whole menu is delicious and interesting. A real traditional neighborhood Cafe. Makes me drool thinking if going back!!! read more

Exactly what I wanted in a burger joint! The food was no frills and soooo good. I ordered a veggie burger and I was impressed that they still have the old school ones (nothing against Impossible/Beyond, it just gets repetitive.) The onion rings stayed crispy and delicious, even after traveling home. I went into a trance and ate them all before I knew what I was doing. read more

3.5 rounded up. I called ahead for a cheeseburger ($6.75), took about 15 minutes. They tried charging me $10.77, I had to speak up and tell them they were overcharging me before they corrected the mistake. Mistakes happen, not gonna mark them down for it. The burger was decent, but not mindblowing. The lettuce and onion were fresh, had a nice crunch. The bun was standard, the patty was decently thick but could use a bit more seasoning. Also it comes with mayo, and I vastly prefer some sort of burger sauce like at In-N-Out. This is the type of place I won't mind stopping by once in a while if I'm passing through, but won't go out of my way. read more

The food is on par with Nations as far as the quality of food. The staff were very nice. The downside is they are way too overpriced for everything. That alone will keep me from returning. read more

The Red Onion - American Near Me - Concord, California

This spot is in a questionable strip mall; however, I must say I would definitely go back. Apparently, this place is owned by the same people as the original Red Onion in the Albany/El Cerrito area. My wife says nothing has changed. The service was really good, though she was the only person working. Our burgers came out with a quickness, and the fries were super crispy. The ratio of condiments to the meat and bread, was outstanding. My burger was cooked to perfection, seasoned well and had a light crisp on the edges. I also ordered bacon, which was crispy but not over cooked. There was plenty of seating, it felt like a bit of an old-fashioned diner. I am sure upgrades can be made, but I would definitely choose the quality of food over the interior. There is plenty of parking and I believe they are open seven days a week. read more
