It's true: the pizza really is that good. Not certain whether it's the absolute best in the city (tastes vary--I also like Zero Zero, personally), but it's a very solid choice and worth going a little out of your way for.
We started out with two glasses of the "Apollo" red wine and the the rock cod appetizer, both of which I personally found totally forgettable. Luckily, they was more than made up for by the pizza. The menu is small, but you can add toppings. We went for a margherita with onions, and it was so delicious we actually ended up ordering a second one.
Knocking off a star because of the restaurant itself. It's really small (only seats a dozen people or so, plus a few tables outside), and people kept leaving the door open when it was cold outside. Given how small the restaurant is, it got chilly really quickly.
