Ive been here twice and both times I thoroughly enjoyed my experience. The service is excellent (my first time both our server and waiter offered to explain the menu fully) and the interior/decor is welcoming with a very neat style. Most importantly the food is terrific, the ricotta is nice and creamy and the pizza crust is a perfectly cooked thin crust. I've had a spinach and mushroom calzone as well as a white pizza with spinach, mushrooms, and Roma tomatoes and loved both. Also, despite not being a big fan of cheesecake, I tried a little of their strawberry cheesecake and it was quite tasty.
Grimaldis's is definitely a place that I recommend.
