Efrain's (I or II) is my only real "must" restaurant when I visit Boulder. The verde chile-- alone or on a burrito-- is a must for those who like authentic spicy pork chile. If possible, the costillas (ribs) are even more amazing. Tequila selection also...More

Efrain's has a large menu of varied Mexican dishes. Everything I have tried has been good. I particularly recommend the burritos. There is a choice of very nice margaritas with various levels of Tequila. Service is very good and the atmosphere is a little nicer...More

We've gone to Efrain's since it opened many, many years ago and I'm a loyal fan till death or until they close for business. If I had to choose a last supper or one restaurant for takeout food to a deserted island - it would...More

Efrain's II is a popular spot. We had to wait for a table for dinner and the restaurant never slowed down while we were there. Located in an industrial building, it doesn't look like much from the outside, but once inside, it is more cozy...More

First time trying a chile relleno and loved it! Massive amount of food served at a reasonable price. Appreciate that they list a heat index for dishes, keeps you from biting into more than you're ready for.

Just horrible. Less than average. Soggy food smothered in low end cheese and sauces. I can get this food in any number of restaurants around the state. Nothing special at all. On the plus side, decent margs and good service. However the restaurant is in...More

I was taken to this place by some old friends that used to eat at Señor Miguels on 28th that disappeared years ago. Efrain's is rumored to be related. They use a bit more cheese than I like but tell them to go light if...More

I love this restaurant food so much. It's a very authentic mexican restaurant with very tasty food. I love their pork chile verde, it's spicy but very tasty. Love to go there repeatedly. I love their burritos, pork chili verde, enchiladas, egg dishes.
