My niece is turning 18 end of March and 9 of her friends want to surprise her with a birthday dinner. They asked me for suggestions. They live in Northern Westchester, however open to NYC. They like all kinds of food and price isn't a huge option. Guess up to $50/head? No alcohol so no worries for that $. Something fun for her to remember. Doesn't have to be fancy...just fun! Open to suggestions.
