Dos Primos is the best Mexican restaurant in the area.. frankly, it is the best Mexican restaurant I have ever been to. The salsa has just the right amount of kick, the queso is very good, drinks are phenomenal, and the quesadilla super gigante is the best quesadilla I’ve ever had! The San Jose sauce is truly something special. Tonight, I tried the taquito appetizer with both beef and chicken varieties and it was great! The service is superb – quick, attentive, and friendly servers, and the owner even came to our table. Highly recommend!!

Fantastic restaurant. Carne asada is phenom and there’s so much food, I’m taking a third of it with me in a Togo box. And I’m a giant guy who eats A LOT.
Service is great, everyone is nice. Very clean. Reasonable pricing. $20 for my meal and left a ~50% tip to make it 30.
Great restaurant – please keep it in business(so I can come back). Treat them the way they treat you!

Good food and great service can’t ask for much more. The portion size on the big burrito was unreal I couldn’t even eat it all. The chimi was a little on the small side but still very good. The shredded beef inside was seasoned well and I would definitely get it again. Chips and salsa were pretty good too that’s always a plus.

Place was boomin’! Our server was super fast, attentive and very, very sweet. Food was flavorful, hot, and came out quick! The meat for the carne asada was seasoned perfectly.
Staff was friendly and the atmosphere was great; seems the chef or owner knows a lot of the locals; he was out shaking hands and visiting with people.
Lots of menu options (with pictures!)
Husband also loved the salsa — said he could drink it with a straw, haha.
Definitely a great place to have some authentic Mexican goodness!

My wife and I love this place. We live in Chesterfield but are happy to make the drive to visit Mario and his great staff at least once a month if not twice. The menu has tons of beautiful photos which lets me try things I normally would not order from the description. Food is fantastic and love their salsa!
