Teen-friendly semi-formal restaurants?
So a number of us (10-ish people, including myself) are looking for a place to have dinner. It's to commemorate our years together as a high school group and to say goodbye to graduating seniors...like a team/graduation dinner, I guess, only that we want to dressed up for the occasion. Does anyone know of any semi-formal restaurants in the city (preferably Manhattan) where a relatively large group of 17- to 18-year olds could go to eat without feeling too out of place?
PS. Bonus if it's Korean.
