Grimaldi's redeems the coal industry. I know what you're thinking; when I heard they had a coal-fired oven, the first thing that came to mind was dirty coal and the energy industry. Well, I don't know how this oven works but, what I do know is that the pizza that comes out of it is amazing. The crust might be the best of any chain restaurant (sorry, Grimalid's, with as many locations as you've got, you can't deny being a pizza chaing). Don't let the fact that the place is a chain dissuade you from checking it out. The ingredients that grace the crust are phenomenal. Their meats are devine and their veggies crunchy and fresh. Definitely worth trying if you like a good pie.
