If you live in the Carnegie, PA area (or would like to travel for an awesome, unique bar), 99 Bottle is a must. You can basically pick out your favorite (or try a new) bottled brew from the freezer. They also have drafts on tap. They have a new menu with classic and crazy bar food items (there're even contests for eating a crazy amount of wings or a gigantic burger).
The staff is so friendly. Once you go there enough, you can tell the bartenders become great friends with the customers. If you don't like beer, they have other mixed drinks ( I had an AMAZING Tom Collins) and then of course the yummy food: cheese fries and choc.-covered bacon for dessert?? Can't go wrong!
