We've really liked Percy's. If you like southwest/ texmex/ sort of Mexican, then you'll probably like it.
I've had the ground beef and the steak, and my wife had the pulled pork and we really enjoyed it all of them. The steak was very good. My one recommendation would be to avoid the tacos as the tortiallas are a bit on the tough, chewy side. But the nachos and burritos are wonderful.
Prices are:
Burrito: $9.99
Tacos: 8.99
Bowl: 9.99
Salad: 8.99

all come with a side of chips and salsa (yes, even the nachos)
