If you want a good pizza - and I mean GOOD, not mediocre, but REALLY GOOD, you must visit Geno's. And just order the small one if it's for yourself...because even the small one is HUGE by European standards, and try the special!
The burgers are mediocre though, there are better places for this, but NO ONE can beat their pizza's. And I've eaten pizza's all over the world, well - a lot of places in various countries.
The place is really cool too, it's almost like taken out of the movie The Goonies, you'll find a few good ol'school arcade machines that are fully operational and brings you right back to the 80s.
The owner is also very friendly, and if it's not too buzy, it's not unusual for her to take the time to chat with her guests, I like that personal touch the place have. You feel welcome there, often they'll even ask you if you want a refill.
