Pizza 51 serves slices so big, they come on trays, not plates, proving that just one piece of pizza can be a meal. Housed in an old filling station ringed by pink neon lights, the shop plays on a Route 66 theme, with a mural of license plates from each state that forms a map of the country. The atmosphere's great, but we're most in love with the less common toppings -- cream cheese, feta cheese, green olives, Roma tomatoes -- and the gluttony-inspiring, all-meat "Cowtown Lovers" slice with pepperoni, sausage and Canadian bacon.
