I have been at this place several times. They've got an awesome Monday happy hour that includes pizza, wings, beer and other stuff. I gotta say, the pizza is much better when you don't get it on happy hour b/c they just reheat slices with new topping on top during happy hour. But the wings...coming from someone who is picky about wings...they are what keeps me coming back again and again.
I think this place is family run and not related to another Grimaldi's in Scottsdale.
Overall, this place is pretty nice on the inside, but can get kind of crowded b/c it is small.
