Ragazzi Pizza is the best pizza place in East Van (for the West Side, my vote's for Brick Oven Pizza on Dunbar).
I 'discovered' this place last year during the Euro Finals; after the Azzuri won a game, during the ensuing parade up and down The Drive, I saw an old Italian car, painted green, white and red, driving up and down the street. The logo on the door said 'Ragazzi Pizza', so I looked it up as soon as I got to a computer, and tried it the next day.
They serve yummy thin crust pizza (I've tried the vegetariana, marinara, and the margherita) and none have disappointed me. It's VERY inexpensive, too; a large margherita was 12-dollars.
On a side note, this place is VERY Italian (as my family's Italian, I notice these things). First of all, there's a sign that says something like: "parking for Italians only; all others will be towed.". The icing on the cake, though, is the guy who shows up everytime we're in there; he drives a Ferrari, wears an Azzuri track suit, comes in, orders an espresso, and then vrooms off. I feel like I'm hanging out at Satriale's.
It's delicious, inexpensive pizza in a very unassuming location. Go!
