Sal & Mookie's is a New York pizzeria and ice cream joint. Their pizzas can be made vegan upon request; their vegetarian pizza and the 'build-your-own' can be made without cheese and you can choose from many veggie toppings. Their Greenwich Village panini can be vegan without the mozzarella. They have gluten-free crusts available for pizzas, too.
