We scored one of the 73 famous Margherita pizzas. Apparently, they haven't gained in popularity so they have yet to sell out. Get one while you can. If you're interested in a traditional Margherita, this is a great pizza. I thought the flavor was good but the center was a little limp and soggy.
While the Margherita was good, what stole my heart was the quail egg pizza. It was perfectly crispy and delicious. It was just all around unique and had a great flavor profile.
Last note:
Mob special - The Boss Pizza + 2 tickets to the Mob Museum = $36. Tickets to the Mob Museum for two are about this price. This is a great deal if you're planning to check out the Mob Museum. It's definitely worth a trip.
