Efrain's of Boulder Mexican Restaurant

Hands down one of the best Mexican restaurant I have had. This one hits top five for flavor, service and style. Got the Efrain’s Burrito and couldn’t have been happier. It was packed with chicken, beef, rice, beans and more flavor than I can express. Put it this way I was using chips to scoop up the sauce and rice. The Jalapeño Infused Margarita was good as well. Can’t beat this place for the food, service and price. Only wished I lived closer to make this a regular go to.

Simple, well-made food. The chile rellenos were very good. This new location is much cleaner and brighter than the old one. Great prices all around & great service from Steven.

Flavorful southwestern cuisine (of course, from the Mexican perspective, it's northwestern). Delicious chilis, shredded chicken. The food can be as hot as you wanted to be, depending on your taste. Enjoy the flavors of the dishes, which are strong but not overwhelming. I enjoyed the delicious blue corn tortillas at the base of my dish. Even the chips they provide for the tables as a starter are quite thick and substantial, paired with liquidity salsa that has a bit of heat to it. The walls gleam with the distinctive turquoise and gold colors of the Southwest, and pottery and baskets from the region line the shelves. There is the overall sense that this restaurant seems uniquely committed to the customer experience, from the food to the overall ambience. If you like southwestern food even a little, come here and you will not be disappointed.

Great Mexican spot in Boulder! The food feels a little more “Tex Mex” style— which I have been missing big time in Colorado. They’ve got good green chili with a decent spice level too. We ordered the Efrain Burrito and Chicken Enchiladas. Both hit the spot. We will be back!

Visited this restaurant on our way back from Rocky Mountain National Park. I thought this going to be mediocre food. Easy access from road, staffs are so nice, very neat place. We ordered Efrain ( super delicious, must try, very big plate), beef burrito ( spicy and delicious, they can adjust the spice), beef chimichanga ( best one we had), vegetarian taco( so tasty, spicy lovers ask for more, their sauce is very tasty). This is one of the best Mexican food we had, its not Tex-Mex, if you are passing through Denver or Boulder definitely try this place. Not at all expensive, quantity is really good. We will definitely try for our next visit.

We LOVE Efrain’s! They always hit the spot with their delicious fajitas, tostadas, and enchiladas! My husband and I eat here once a week, and it never disappoints. It can be pretty busy on a Friday or Saturday night, but we’ve never waited all that long on busier evenings. The service is always top-notch and everyone is very friendly and kind. I also love that they keep the chips and salsa coming! I absolutely love their Boulder Margarita, and they have about 15+ different selections of margaritas to choose from so everyone is happy! My favorite meal is the chicken fajitas. You will not be disappointed-they give you a massive portion with lots of delicious guacamole, beans, rice, and sour cream to enjoy your fajitas with, which I really enjoy. Best fajitas in Boulder hands down. My husband loves their blue corn enchiladas. I would also like to mention that they are gluten free conscious, and have many items that are 100% gluten free to choose from! This is a Boulder gem of a restaurant!

We had a great meal at Efrain’s tonight complete with a rainbow view. Do take the heat readings seriously! The Efrain’s Famous Chile Verde bowl was fantastic and earned the 10/10 heat scale! The Efrain Burrito was gigantic and delicious. My kiddos were happy with their hamburger and chicken tacos. We hope to be back soon!

We dropped in for dinner and drinks after hearing about this place. It reminded us of our favorite family-run Tex-Mex joints back in Texas. Plentiful and fast chips and salsa, well-priced strong margaritas, and hot, flavorful, home-cooked food. For us, Efrain's is the perfect "comfort food" restaurant, and we will return again and again!

Phenomenal Mexican restaurant with a great menu and amazing tasting food. The restaurant is owned and run by a local family that love what they do. The fajitas were delicious and I liked how they gave raw onion as one of the fillings. The meat that came with the dish was a generous serving and delicious. Would recommend this place to anyone. Be warned though, this place gets really busy, so come really early and prepare to wait. But grab a margarita while you wait.

Really amazing Mexican food. Great quick lunch with friendly staff. I was also a bit shocked with the prices recently. My bill was about half of what other restaurants around are charging. I had to do a double take as I thought I was given the wrong bill. Always a crowd pleaser.

I love this small family run business, their food is delish! And their margaritas are so tasty. Somewhere on their land they also have a bee hive that produces honey you can also buy here. It makes a great gift to take home after a great meal! My favorite are the cheese enchiladas. Their red sauce is addictive and I love it with chips and as a topper for the rice and beans.

Had an incredible dining experience at Efrain’s of Boulder Mexican Restaurant and Cantina! The food was an absolute delight – every bite bursting with flavor. The salsa was so addicting, it deserves its own fan club. 🌶🤤

The service, led by the fantastic Fernando, was beyond stellar. His personable approach, helpful guidance, and friendly demeanor made the meal even more memorable. A big shoutout to the entire team for creating such a wonderful culinary experience! 👏🌮

I’m honestly blown away by Efrain’s and their staff. The service was very prompt and we had gotten our food in 15 minutes from the time we sat down. Chicken tacos and flautas are delicious and the perfect portion size. I would absolutely come back again! Thanks again to Efrain’s staff for working hard, making us feel welcome and for the delicious food! Can’t wait to come back!

Very well decorated restaurant. Very attentive staff and affordable prices. The flautas were perfect, the outside crunchy and the meat was so tender for both the beef and chicken. Be sure to try the Pina Colada Margarita! The absolutely best margarita I’ve ever had

We got lucky and found one of the best Mexican restaurants in Boulder (that's what the other guests told us while we waited). I got the Efrain Burrito = "delectables covered in who knows what" is the description. I took the chance and it was delicious. House Margarita was good. Wait staff was attentive. The only negative is the place is small and demand is high, so expect to wait a bit... worth it.

This is a must on your Boulder to-do list. Everything is great but if you love Chile Verde then Efrain’s is worth the drive and wait (if there is one). Don’t be thrown off by the close dining quarters and the lack of fancy decor. The food speaks for itself and your stomach will thank you!

Great food for a great price! Their Green Chile Pork Stew was flavorful and very spicy! Their enchiladas were tasty and filling. The atmosphere was lively and people were waiting up to an hour for a table - so did we and it was worth it! The service was also great and the staff was very friendly.

Excellent food and service, highly recommend for authentic Mexican cuisine. My sister has been raving about their food for forty years. Although this may be new location, it has same great food.

Our server Fernando was awesome. He had great food and drink suggestions. We are from out of town and absolutely LOVED this place. Food and drink we both amazing. Senor Efrain was also there, it was great watching him interact with guests .

The food was very good. It came out fairly quickly and was served hot. We had free chips and salsa to help us wait. I got a margarita also that was tasty.
