Absolutely amazing, I cannot say good enough things about this place, the people, the service, the food. It’s all amazing! I got the Carne burrito with green sauce and it was absolutely delicious!

★★★★★ 5.0 Michael Levine · Nov 2024

Huge portions, friendly staff, ask for the extra spicy salsa. So good. Hand made fresh tortillas. Everyone enjoyed there dishes. Definitely stop in if your in for a nice Mexican dinner. Not to fancy in the inside but the food is awesome.

Sergio has been around for over 40 years. He had a really nice restaurant in Glendora, Ca but he closed during COVID. I'm so happy that Sergios is still open. Super good food.

It was mine and my husband's first time to Sergios restaurant. We were there on Tuesday, it wasnt too busy. We took a table wherever we wanted as we were told. The waitress came right away with chips/salsa and took our drink order. Our beers were nice and cold. My husband ordered a fajita salad, yes a fajita salad which I've never heard of. He really enjoyed it. I ordered a 1 taco plate. My chicken taco was tasty and moist, the rice and beans were excellent. The red/green salsa were tasty and not overly hot. We met the owner Roberto, such a nice man and welcoming. We were asking questions about the history of the restaurant and he told us. It was interesting. We will definitely be back and we will back Sunday to try their menudo 😊. Thank you Roberto!!

Super salty, inedible burritos. I ordered a carnitas burrito no onions, no cilantro, it's full of it, i didn't ask for both to be wet burritos and both were wet and super salty. The carne asada tastes like they poured all the salt into it. The carnitas are also super salty, the chicken flauta has no flavor. The salsa has no flavor just all heat and unusable. Pretty upset. I spent $40 and I can't even eat it. The chips are ok they have no salt or flavor but a nice crunch. The seating areas are big and nice. But I won't recommend to dine here. What a waste of time and money. I was watching them make the food all I saw was food coming out of plastic bags. Nothing tastes authentic or Mexican from my standards. Owners should be ashamed to put this food out into hard working people's plates. H
