In addition to Mellow Mushroom, Z Pizza and Clever Crow, Element Pizza Bar also cranks out some yummy vegan pizza. They don't have any vegan specialty pizzas but they have Daiya available and their menu says "Vegan and vegetarian option available, ask your server." The crust was excellent, nice and crispy after being fired up in a stone oven. A nice pie all around. Check out the crispy chickpeas, too :)
