Oh god. I hate you Stichawl. As a native NYCer, I was lucky enough to live in the pizza capital of the world. Now in HK, finding an authentic NYC-style slice is not quite mission impossible, but certainly not an easy task.
Thanks for making me miss home...
I go between 2 extremes of crusts: "designer" pizza with uber thin, crunchy crusts baked in brick ovens and deliciously thick sicilian square slices covered in mozarella. There is a local joint in Flushing, Queens near where my folks live that I have been hitting for over 20 years. No idea what their secret is, but their sicilians are the best I have yet come across. Gotta be the cheese - indescribably delicious.
Close third place: those enormous incredible deep-dish Chicago style pizzas. I nearly passed out when I had my first in the Windy City. Awesome.
Toppings: Pretty much everything, except pineapples [I like my pizzas salty, thank you]. Jalapenos, suasage, pepperoni, mushrooms are staples for me. When in designer pizza joints, I gotta have prosciutto! NYC also has a ton of places doing theme slices: mexican toppings, ziti slices, buffalo style, you name it!
And of course....
CHICKEN!
