I think the pizza here is some of the best I've had, and I ate a lot of pizza in Italy too. Grimaldi's could use a small price adjustment. I would go there far more often if they were 15-20% lower on the price. They'd still be more expensive then the normal NYPD and such but it would be worth the cost... as it is right now, I eat there once every 6 months since it is expensive for pizza.
Picazzo's is of similar quality and price (except when you use Restaurant.com certificates it is a better price). Grimaldi's is closer so I go here more often.
