Guanciale and Egg pizza at Robertas!! Its amazing. They don't have it on the regular menu but will make it if you request it. It basically has a whole egg in the center and very thinly sliced pieces of guanciale.
I'm a fan of otto clam pizza and their aglio olio pie. I love the prosciutto pie from motorino I also love the grandma from delizia on the upper east side. Super thin. Super delicious. I also like the mushroom, pea, pecorino from rubirosa.
I haven't been to Keste in some time, but I loved their Pizza del Papa, if that's what they were calling it then, when it was with butternut cream, artichokes (not peppers or zucchini) and smoked mozzarella.
At Arturo's, I've liked their clam and mushroom pizzas a lot.
I know Otto is not a favorite pizza with a lot of CHers, but I love their truffle and egg pizza when it is offered. From their regular menu, the taleggio and funghi pizza is wonderful.
