There are a lot of pizza places to choose from and Northern Hillsborough is a pretty big area. All of the regular chains are available, but I would recommend trying some of our local places. Cappy's Pizza made national headlines for their no unruly kids policy, their pizza is good though. A couple of random places that are worth mentioning around Northern Hillsborough are Brickhouse Pizza in Northdale, Heights in Seminole Heights, and Slice Masters.
My favorite local place has to be Wood Fired. If you are looking for more than your standard NY style pizza, this place is great. They have unique pizzas that you will not find anywhere else in town.
