I like how they do things at Sam's. It's upstairs in the Biltmore Mall but they manage to be the most laid back of all the bar/restaurants in the area. They convincingly do mexican food in a southwestern style with all sorts of interesting twists and spins on dishes that I haven't seen before. The chicken enchiladas are dee-lish and the margaritas are some of the best I've had.
Service is touch and go when they're busy but for the most part I've always been content with their staff. It's a pretty good date spot and the prices are reasonable, especially considering the caliber of the food they serve.
