At our office we have something called "The Panzo Challenge", which requires the participant to finish their Nonna's Oven panzerotto in one sitting. Many have tried, some have failed. Who can blame them? it's essentially a small/medium pizza wrapped in half! And how!
Restaurant size:
When Nonna's Oven first opened it was pretty small and was always occupied by Honda employees. They've since expanded their size and offer more tables and seating!
Portion size:
The food-to-price ratio is definitely favourable for your buck, and you'll definitely be feeling full for many hours, if not the rest of the day.
Service:
The ordering line usually extends to the entrance at around lunch time, so there is a bit of a wait to get your order in. A server will bring your plate and cutlery to you, so you just have to wait a little while longer. It will be worth it though.
