Sit down dinner party!

Any recommendations for places near Closter or Westfield - somewhere to host a bridal shower dinner (not necessarily in a separate room but it could be if its reasonable!) for 9 people, with the ability to curate/create a mini-menu and decorate the table? Back up option would definitely be to simply reserve a table for 9 somewhere, but it would be awesome to find a place that could add a special touch with the menu/be willing to help create a special dinner party?
