As far as chain restaurants go, this one is top notch. It has everything you could want in a food venue. Great appetizers, huge portions, great drink selections, and more.
I like the fact that they make "strong" mixed drinks, and they usually have some great local and seasonal beers on tap. The Guac-a-Tony appetizer is by far my favorite. I even know a guy who, the first thing he does when he comes in from out of town is orders this. Just make sure you have more than two people in your group before trying this appetizer otherwise you won't be able to eat anything else.
Indeed, they make great pizza, but there is so much more to this restaurant than their pizza. In fact, I don't remember the last time I actually got a pizza from them.
