Carrabba's, Marcella's, Polaris Grill, Giammarco's, Mitchell's, Hyde Park, JAlexanders (must make reservations), J Gilberts.....somewhere classy....do NOT take her to Red Lobster or Olive Garden (too cheesy)....take her somewhere she wouldn't expect to go, and that has a little class.....Have a couple of option for after dinner and ask her to pick...somewhere fun like D&B and then another place that may be a little more quiet (in case she prefers that and you don't know it) If she won't pick, then you'll have to man up and pick....
Good luck, and report back on Friday night....or Saturday Morning
