I went recently, and Paulie recommended getting a dell boy, but with hot honey on the side to try it as a hell boy. Hell Boy is better, IMHO. But i understand where's he coming from.
We tried a lot of pizzas... some of our favorites were:
Monte Cristo (seriously good)
Rooftop Red (a crowd favorite amongst all of us)
I would honestly leave off the Regina, as his ingredient combinations are what really stands out more than anything from my visit. Get a dell boy with hot honey on the side if you can, and a Rooftop Red, and a Monte Cristo. Those were my clear favorites.
