For my money Piece is the best place to go for thin crust. Besides the awesome pizza and variety of toppings (I love the fact that the bacon pizza has entire strips of bacon instead of bits) they also have top-notch beer and a great atmosphere to meet people with the shared tables.

True story - a few years ago I ordered 2 pizzas for pickup. When I got them and paid I took a peek and noticed one of the toppings was incorrect. I pointed it out and they were super-apologetic and nice about it and asked me to wait while they made me a new one. Ten minutes later I had my corrected pizza and they gave me the entire order for free, even though I did not ask for it or complain about their mistake. Now that's customer service!
