There's not much that doesn't take place at Frankfurt's international variety theater, the Tigerpalast. Guests are entertained by international cabaret performers and the Palast's own variety orchestra. There's an excellent French restaurant that has been awarded a Michelin star, and the cozy Palastbar, under the basement arches, looks like an American bar from the 1920s. Despite pricey show tickets, shows often sell out, so book tickets as far in advance as possible.
It's closed Monday.
