Best slice in Queens can be found at Caruana's aka Joey's on 69st & Grand Ave in Maspeth
This place had been around forever and is a slept on gem. They have the only sesame slice that I know of and tates like great Italian bread with cheese and sauce. Their pan pizzas aka mini pies are outstanding and always deliver. Caruana is an old man and has retired and sold the place to Joey one of his long time pizza makers, hence the name Joey's. Caruana is also responsible for another outstanding pizzeria in Carlo's on Metropolitan Ave and 73st. His sons run the place and it has been around for 40 years. Let me add that Caruana has a great sicilian as well. I have been eating there for a while and the place has always stayed the same. The decor is wretched but don't let that stop you. Try a sesame slice, mini pie, and sicilian.
