Leonardo's Pizzeria (1st St location) has hands-down some of the best pizza in the 'Couv. The crust taste great and they are very generous with the toppings. I've created a loyal fan base of Portlanders now willing to cross the river for a slice. The only complaint, and it's a BIG one, is the service. The staff consist mostly of people in their teens to early 20's and there never seems to be any supervision for them. The tables are always dirty and un-bussed, getting the attention of the wait staff occassionally requires flares and sirens, and they have been known to get the orders wrong, if not completely lose an order during the dinner rush. I highly recommend getting your pizza to-go and make sure they see you are waiting.
Pros: Great Pizza, yummy food
Cons: bad service
