I am in my mid-twenties and planning an upcoming birthday dinner. It will be mainly couples in their twenties and thirties and also a newborn baby. Does anyone know of a place where we won't be too out of place if we dress up (those of us not with the child will be going out afterward), but that is a relaxed enough of an environment to bring the baby? Classic New York spots, leaning toward inventive American or fusion foods would be great. Thank you!
