The mothership. This is the site of the slice shop that started it all in 2009. The original shop has expanded since then to feature a full-service dining room and bar on one side, and Enzo – our cozy wine and pizza bar – on the other. A great location for a quick pre-show slice and a beer, or a night dining out with family and friends.
Mixed reviews on pizza quality; some praised unique flavors and crust, while others reported greasy, burnt, or undercooked pizzas.

There was no line and frankly, I can see why. The pizza was swimming in grease, burnt on the bottom and the cheese tastes of melted plastic. My husband and I are in town for a concert and made the unfortunate mistake of popping in, as the business as a whole is rated 4.5 stars, I had hope. The key word - had: the sauce was both acidic and flavorless, the slices themselves were burnt and swimming in grease, and the service staff was hardly engaged with each other - let alone us. The bar was on the floor and somehow, I am still disappointed. 30 dollars for four slices of purely inedible "pizza" and two sodas.

Loved the vegan pizza, and they have vegan gf options. You can sit outside with a dog. Nice people.

Ordered Cary-out online, easy, even set my pickup time to be later than ASAP.
I ordered the Ricotta and Basil, adding tomatoes because I wanted an uplifted Margherita pizza.
Crust and ingredients are top. I looked back at this photo and got hungry.
Worth the hype. Large will feed 3-4 for sure.
