Been to 3 or 4 other buid your own pizza types of places. Comparatively, I would say Project Pie has less toppings options. However, they do have prosciutto, which I haven't seen at any other build your own pizza place.
I chose one of the pre-designed pizzas which had prosciutto and caramelized onions. Not sure how I felt about the salty/sweet contrast, but the pizza itself, crust and all, was good.
