Congrats to your son. Something fun might be a progressive dinner at some of his fav restaurants. First stop appetizers and drink, then next stop the meal, then next stop dessert, and the final stop home or
Another fun thing might be to go to a comedy club...we took my daughter and her boyfriend there and we all had a blast. They have drinks... Try Ad libs not too expensive or some of the other comedy Improv or Commedy Coner I think it is in Arlington. HAVE FUN! You could do a nice dinner at home and then go to the comedy club for a drink and laughter!
