A place like Grace in TriBeCa?
Grace was one of the few places to serve food after midnite. As far as bars downtown there are a few that have room for as many as you want but no real food. places like Patriot, Raccon, Reade St., Walkers can handle a decent size crowd and has good food. Theres no place really like Grace. Yaffas is empty enough and has apps pretty late.
