We literally stumbled on Luigi's trying to find the Letterman Studio's.  This was our first meal in New York and hands down was the best pizza find of them all.  We tried all the pizza places locals and books recommended, but none could touch Luigi's.  The staff were not very friendly, but with food like that, who cares!  It's worth going back to New York just for their pizza!
Pros:  Food, Price, Location
Cons:  Service, Unfriendly
