First of all, I love thin crust pizza from a coal fired oven. Grimaldi's on Scottsdale Road is tasty, crisp and reminds me of the great pizza from Philly. The '2' is because of the dumb schedule and poor service.
We stopped recently for lunch and had an excellent pie. But the service was really crappy, it took 15 minutes for someone to wander by and collect our order. Then we wait another 15 for drinks, and finally the pizza showed up. No one refreshed the drinks or came by to check on us. AND, there was only one other party in the place!
The other item is availability. They re-stoke the fire in the oven at 4:00 PM. So you can't get a pizza until 5:30. Now if you want to stop on the way home to get a pizza for Friday night dinner, forget it.
Dumb.
