We've been visiting Efrains in Boulder for a couple years now. We love the yummy Mexican comfort food and delicious margaritas. Generally the service has been good over the years - Cameron for one has always been friendly and a great server. There are also...More

Efrains is one of those classic boulder places that is a little out in the sticks but is totally worth the drive. It gets crowded but it's totally worth it. I would recommend this place to anyone trying to get a cheap Mexican style dinner...More

WOW. Amazing green chile. For my first visit years about, I tried their FAMOUS CHILE VERDE BOWL. The flavors were out of the world, but the heat level was off the charts. Yesterday I ordered CHICKEN SUPREME ENCHILADA and had them smother it with their...More

This is a very popular Mexican restaurant on the east edge of Boulder, just off Arapahoe. Waits can be long for dinner in the summer, but they do allow you to enjoy your Margarita in the small area outside. In the winter, you may have...More

Really enjoyed visit to this traditional Mexican eatery. Starting with chips and saucy and cold drinks including Mexican beers on tap and excellent Margaritas everything was top notch. This is not a fancy place. Very laid back, good food and good service. Watch the menu...More

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.
