There is a Chuy's!
A couple other of my favorites are
La Tienda--casual, pretty authentic, Mexican that is way too good..I like the chimichanga, its awesome. and near the vet school!
Boca Fiesta--also Mexican, and also great, less authentic and less casual. I aalso think they have some unique things like gator meat
Satchels--famous in Gainesville, its a funky pizza place, and they make their own soda
Dragonfly--kind of a trendy sushi place, a little on the expensive side, the dragon roll is awesome
The Gelato Company--A. awesome gelato B. a really good place for lunch, they have good sandwiches etc
Mi Apa--casual cuban, can sit down or they have a drive-thru
Civilization--go for brunch
The Flying Biscuit--amazing breakfast
Piesano's--pizza
Blaze--this is brand new, you can pick the pizza toppings and they make it right in front of you, it takes like 5 minutes because of the thin crust
A couple more that are either chains (at least in Florida) or are quick and more for a quick bite
Bento--asian
The coop--fried chicken/chicken tenders
Burrito bros--self explanatory
Designer greens--salads and sandwiches
I can't think of anymore right now..but as you can tell, I love the food in Gainesville
