As a frequent visitor to NYC and a huge fan of the famous Lombardi's Pizza I am a firm believer that coal fired is the undisputed champ of Pizza. Grimaldi's is a direct descendent of Lombardi's beginning in the 1930's and it shows as they have remained true to their NY roots.
I make it a point to over order when I go there so I have plenty to bring home. I always start with the Caprese Salad or Anti Pasta platter, either way I get that amazing fresh mozzarella that dances across the old taste buds that can't be described in a PG rated review.
They have done something to maintain the same consistent crust you won't find anybody else doing. They have a special tap that creates "Brooklyn water" specifically and only for the crust.
The fresh mozzarella and sauce speak for themselves, if you feel Pizza Hut makes a great Pizza, then go to Pizza Hut. You aren't qualified for Grimaldi's.
A++++
