I LOVE pizza, but I have always considered myself a deep dish girl until I tried Grimaldi's. I would probably never have tried it if my co-workers hadn't ordered it for the team for lunch one day. It's a little expensive for pizza and the restaurants are usually pretty busy, but after having it I was immediately hooked. My favorite Grimaldi's toppings are the italian sausage and ricotta cheese, but also love their tiny pepperoni. Delicious!
I've been to both the Scottsdale Quarter and Old Town locations. I'd say the pizza is equally great at both locations. The Old Town location is a little larger, but super busy any time I've been there.
The only negative I have about Grimaldi's is the way they charge per topping, regardless of the size of your pizza. Chicken is going to cost you $5 whether you order a small or a large, which is strange to me. If you order a small you're obviously getting significantly less chicken.
Overall, despite it being a little more than I generally want to pay for pizza, it's totally worth it. The wood-fired taste and perfect thin crust make it really difficult not to go back.
