Quality isn't great, but price is cheap.
Went one, had a burrito bowl. Overall I've had tastier (eg. Tejano) but there was a lot of different ingredients to choose from, and everything tasted fresh. The size was good too, I eat fairly big portions and I was full after a large bowl.
I chose the tequila steak, but I don't recommend it. Didn't really taste like anything special.
FYI, there are a couple of 1 star reviews. I agree this place is not a gem, but no way does it deserve 1 star. I greatly doubt the integrity of those reviews (both profiles were created in the last week and left only 1 review?!).
