Here's my review of Beyond Sushi on 14th Street:
"I really like the sushi at Beyond Sushi, but it makes me miss Soy and Sake all the more. Beyond Sushi creatively makes different combinations of delicious vegetables and toppings to come up with their rolls. My only complaint is that the rolls are just vegetables, so there are very limited protein sources. There may be one or two rolls that have tofu, but that's it. Otherwise, a very yummy place for vegan sushi!"
The Green Roll in Chelsea Market has the same food, but even less seating space. There are seats in the markets but those are shared among the different vendors there.
Cons: very limited seating
