Chuy's was pretty good. Seems like all of their locations are pretty similar. I think they'd be best known for their cheap margaritas... $2 pints, $4 small pitchers. They aren't too strong and come from a mediocre mix, but if you're looking for something sweet and cheap its a good bet.
Free serve-yourself chips and salsa are pretty good.
As for food... pretty decent prices and okay to good food. I wouldn't say its authentic Mexican, actually I think the menu is a bit confused. But the food is good overall. It's a place we'll go to every month or so.
