I ate so much Pizza Shack pizza growing up I never really thought much about the quality. When my family would order pizza, it was Pizza Shack or Celebre's. As I got older I eventually decided that given the choice, I'd take Celebre's over the Shack any day of the week. That's not to say Pizza Shack is bad; on the contrary their pies are consistently good. There are just plenty of better options around the city. If they're in your area then by all means give Pizza Shack a try, but they aren't exactly worth going out of your way for.
