While the food is acceptable, the service is quite lacking. During a lunch visit the server made minimal contact with us, only enough to obtain our order, deliver the order and present the check.

When in Boulder, you must try this place. After arriving in Boulder, we were very hungry and asked friends where to get something to eat, they suggested Efrain's and what a good suggestion it was. I ordered the beef enchilada's and boy was I in...More
