Certain times in history have left strong images in our minds, whether we were alive during the period or not. What do you think of when you hear about the Prohibition Era or Flower Power? What about the Victorian Era, the Renaissance or the Roman Empire? Translate that into a dinner party idea.
A 1960s Flower Power party can mean tie-dyed placemats, beads in the doorway and endless music choices (think the original Woodstock Festival). If you tie in the food from that era, you're probably talking comfort foods like meatloaf and mashed potatoes, with whipped cream-topped gelatin for dessert. Add to the ambience by purchasing nostalgic toys for guests to tinker with before and after dinner. It doesn't hurt to dress the part, either; bell bottom jeans and a fringe vest would be right on, man.
