Sorry negative reviewers. You have no idea what you're taking about. Backyard Taco is one of the best, authentic taco outfits around. If you happen upon the original location on University, you'll see that it is always packed. There's a reason for it. I've been to the Gilbert location, and to be honest, was a bit nervous that it may lack the quality of the original, But not at all. They prepare meats and ingredients the same way, with the same taste.
This place is awesome. Far from "white people" tacos that another reviewer claimed them to be.
