I've been ordering from Grassano's for over a year. I always get delivery so I can't comment on their location. Their thin crust pizza is quite tasty and I think it's mostly the sauce that makes the taste stand out from most of the other pizza I've had. They put the toppings all the way to the edge of the pizza, which I think is a nice change, once in a while.
As much as I like their pizza, I absolutely love their pizza puffs and anyone that gets anything from Grassano's has to try a pizza puff. You have to be careful when eating them as the cheese and sauce can be very hot and very messy. They're pretty big too, so they definitely fill you up.
Delivery times are pretty good. They're a few miles from me and they usually take 30 to 40 minutes to get to me.
Lastly, the price, IMO is pretty cheap with the coupons they give you. Somtimes they tell you over the phone to have the coupon ready but the driver never actually takes it. I suppose if they ever did take it, you would have another one on the new menu they give you with the order anyway.
