If you are a vegetarian and 1) Live in or around NYC or 2) are planning to visit NYC you must pay a visit to Hangawi. If you're a budget conscious college student, save up the 50 duckets that it will cost you and take a camera for the memories.
If someone else is paying, well then yippee! Get the mountain roots appetizer --- it's off the chain, maing. The head straight for the grilled tofu in seaweed sauce and/or one of the hot stone bowls (known "be bim bop" to the hardcore).
When I visit NYC, I feel deprived and cheated if I don't get a chance to eat at Hangawi. If you're travelling solo -- have no fear --- go by yourself and forget about feeling awkward. It's all cool at Hangawi.
