The staff are pretty nice, not outstanding, but not rude. The food, though, is outstanding. Love the sauce, you can taste the sweetness in the sauce. It doesn't taste like it came out of a can. The toppings tasted fresh and not mass manufactured. The crust was great too.
I am not usually one to get too excited about chain restaurants but Grimaldi's is worth it for a really good, gourmet taste, pizza. Try one of their wines with it too.
