I visited Otto last Sunday (06.01.13) with my uncle who is a coeliac vegetarian, he struggles a lot more than me with a standard vegan diet. There was one vegan pizza on the menu but the friendly dude that served us said all vegetarian pizzas can be made vegan (complete with the awesome cashew-cheese) and explained how everything works. We both went for the artichoke & spinach pizza (they change daily I think) done as vegan. The bases of the pizzas are made of corn so for all they are not that big they are extremely filling. We washed this down with a gluten free pilsner and left very satisfied. I think someone from Otto may have read the last review as they now boldly advertise that they will use the same pan for orders unless asked otherwise. All in all well impressed!
