There will probably be a bit of a wait, but it's worth it. The margaritas are tangy and delicious. You can enjoy them with the salsa and chips, which will get your mouth buzzing. The menu is full of authentic Mexican food choices. But, you...More

Very authentic Mexican food with tasty Margs. There is usually a little bit of a wait on the weekends but it's worth it. The chips and salsa are delicious, the green chile is incredible, and if you have the guts, the spiciest salsa is great,...More

Great food and margaritas. Attentive service. I'm fond of their menudo and have never been disappointed. Hubby loves the ribs and the burritos. Went to this location to have lunch and to purchase gift cards, unfortunately gift cards are not available at this location. Went...More

I haven't had green chile in a few years because it's always made with flour and I didn't realize how much I wanted some until I got the costillas (ribs) here. They were smothered in gluten free green chile and accompanied by beans and potatoes...More

This place is definitely a dive in a industrial park, but the food and margaritas are great. I get the Mondongo plate of beef pieces in a chili brown sauce with rice, beans and flour tortilla. My wife gets the enchiladas with hot sauce on...More

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...More

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....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...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...More
