This hole-in-the-wall is located on a relatively busy commercial street so it is not really hard to find. There was a line but it went quickly, and they made our vegan pizza to order in 10 minutes! The premade sandwiches are also really delicious! Their fake cheese is made from rice and does not have an aftertaste--very good. There is nowhere to sit, but we took the pizza to the plaza and ate there. Fed the whole family of four for 20 euros, which in Venice is a bargain. Gelato stand with two fruit sorbets right next door to this place. Located very close to Piazza San Marco, 5 min walk.
Cons: nowhere to sit
