Efrain's is solid, traditional Mexican. We always enjoy the enchiladas, which are absolutely drenched in melted cheese. The plates are wicked hot, so when they say "don't touch,": they mean it. The spicy green chili is just about unbearably hot. Low key atmosphere matched by inexpensive menu. Good food.

To look at it, you'd not think much of going to eat at this restaurant. Situated in a light industrial mall, the exterior of the building is extremely non-descript with the exception of the crowds of folks sitting and standing around, waiting to eat inside. We ate here on a Friday night and it was busy -- 45 minute wait,... More

Visited Efrain's many many times. Their traditional dishes are excellent, blue corn enchiladas, with or without chicken are right out of Northern Mexico. The Efrain is great, but very fiery. I have chosen not to move on the Tex/Mex part of the menu and will not comment on it. I have tried both steaks, which again are in a Northern... More

The food and the service was horrible! I would never go back here. My husband and I had Taco Bell a few weeks later and it was 1000 times better than this place!

Found this place solely by chance and when we drove up and saw the look of it, we nearly drove off. Inside isn't much better as it possessed cheap tables and chairs, not all that clean and not that welcoming. However, clearly looks are deceiving as the food was very good. Huge portions and good flavors. Authentic food without the... More

The wait for a table on a Monday night was well over 20 minutes. The place is busy and so seems well supported by locals. The food was okay and there was a lot of it, although I would rather it less better food than more average. Having said that, it was far from the best Mexican food I have... More

This place has great food and margs. However, I have never been to an establishment with such terrible service. Good thing the food is great because I would never come here for a great dining experience.

Efrain's is a local favorite for good reason. It is hiding on the industrial side of Boulder in an inconspicuous building and retains the feeling of a local Mexican restaurant. The food is excellent, with flavorful and spicy green chili, and the prices are very affordable. It doesn't try to present itself as a fancy restaurant, but exceeds expectations on... More

Authentic Mexican fair. It's always hot and the service is always great. It's not a big place-kinda cramped really, especially at dinnertime. Great green chile and really good red enchilada sauce. The salsa is really good, too. Not much for ambiance, but it's usually lively.

Tucked back in a "flex" office park a few miles from downtown Boulder. We live close and visit 2-3 times a month. Depending on your timing you might have to wait to get a seat. The layout is cramped and service can suffer a bit due to tight spaces and too many patrons. Still we have no issue as the... More
