My 17 year old nephew will be visiting NY from the UK with his politics/government class. They have one night free and the chaperone has decided to let them loose in Union Square. I am taking my nephew and a couple of his friends to dinner but would love to give the chaperone a list of suggestions for the other kids so they arent disappointed by their NY experience. Doesnt have to be super cheap but I was thinking BBQ/Mexican/Burger/Curry/Thai. I think we can stretch to walking distance from Union Square. Any great ideas out there?
