Pie is a new Pizzeria just south of Union Square on 4th ave between 11th and 12th st. The pizza is sold by the pound which makes for a chaotic and stressful ordering enviornment as none of the per pound prices are posted. People were awkwardly gesturing for sizes and shapes they wanted cut from the long slabs of pizza. The slices are cut to whatever size you'd like by a server with a pair of shears and then heated in a mini pizza oven. The crust is cracker crust thin with little flavor aside from the occasional welcomed charred edge. Overall I'd say it's the best quick fix for a slice craving in the area. Still I got a water and some randomly shaped pieces of fresh mozzarella pie, ricotta potato and walnut pie, and a mushroom pie which all totalled weighed in at a whopping 9.50 for about three small pieces. An interesting concept but they need to work out the kinks of people being shocked at the weigh in when they've already selected their slices and had them heated. Out of the three I tried the mushroom was the best. The crust was pretty much just a bland handle and the mushrooms provided a bit of earthiness and went well with the slightly sweet sauce.
