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!
