The pizza is sold by slice. Its a very small place, and i dont think they sell anything else but pizza. they dont have a place to sit and eat. however, they do have about one or two tables outside but no chairs. I recommend to pickup a couple of slices and head to the Trevi Fountain(very near) and eat. many vegan toppings, about 4 to 5 different vegan pizzas to choose from. the pizza is amazing. And its not expensive!!
