I am looking for a fun place to have a birthday party. Most guests will be in their early-mid thirties - want something not too expensive, preferrably on upper west or upper east or midtown - but will take any recommendations - anywhere in Manhattan or North Jersey. Type of food doesn't matter but I want a place that is fun, good ambience, ideally some dancing, or some good music, show, something fun going on so that it is not just sitting and eating. Please recommend! TIA.
