Decorate with Art Deco lights, huge cardboard Art Deco sculptures and minimal floral table-toppers. Keep colors dramatic but minimal.

Have a band that can create the old night club sound. Have a "Live from the Hotel Ritz" radio broadcast with a DJ introducing crooners who sing sultry ballads and commercials from the radio days.

Serve dishes from the recipes of the time period. Have a Hotel owner / Host dressed in a tux greeting people and keep the evening moving.
