Game Night
NEVER GROW UP. Make your favorite childhood board game the theme for decorations. Offer a "Kids Menu" for food and drinks with chicken fingers and grilled cheese, then roll the dice until you're ready to put it away for another 10 years.
UP THE ANTE. You're a grown-up now, so it's okay to add some spice to that old board game with a friendly wager. No, not the kids' braces money. A chip that says "IOU One Clean Bathroom" is enough to make anyone sweat.
Make your guests all feel like winners! Prepare goody bags that bring your guests back to their childhood.
