I'm a fresh pizza freak and North of Brooklyn does that fresh chewy-tender slices thing much better than anyone - it's fancy THIN slice. Tiny place and you rarely get more than one to three options because it all sells so quickly after made.
Service and attitude can often range from rude to functionally retarded - ie. hipsters with head up their posterior - but be friendly anyway, as this is the Terroni-level experience without buying the whole pie. Hot delectable 'Za, and I would really stick to the tomato-based ones, Basil Margerita and Oregano Pepperoni that has real meat in the sausage. They don't really cut it with the Putanesca and Bianca which seem flat tasting (no pun, muahah).
You might need two slices, and you might need repeat visits. Worth the slightly fancy price.
