Gino's was the first place I ate during my short trip to Venice as it was close to my hotel; it was OK. It had two vegan pizzas on the menu, plus pasta and salad options.
I went for the Siciliana because it had no cheese but also had olives and capers. It smelt lovely, and the flavours were nice but it was extremely garlicky and a bit too crispy. It was the only pizza I ate during my visit so nothing to compare it with, but I've had much better in the UK so I'm assuming it's not the best Venice has to offer, however it's a pleasant place to visit for a quick bite to eat.
Cons: Nothing marked as vegan, Not great quality
