The food is so-so, not great, but not the worst I've had. The enchilada sauce is obviously from a can, but, like I've said, I've had worse. The salsas sit out all day and tend to taste stale.
The service is quick and the prices reasonable, so it's an ok alternative to fast food.
Watch your bill. The last time we went we were charged almost 14% sales tax. Either someone doesn't know math, or felt they were entitled to a tip and included it in the check.
