My favorite last year and 20 years ago and still my favorite today.
Just talked to a kid that came from Italy and there is a place he loves called Steve's Pizza in North Miami, FL of all places. Says it's very authentic and simple. In fact he drove down there just for the pizza. I haven't tried it but I'll have to when I have a chance.
