If you’d like to be more adventurous, one easy way to start is through food or perhaps even a customized cocktail. Whether you’re traveling abroad or exploring within your own town, you’ll be sure to find a place that serves something you’ve never had before. It’s even more fun when the restaurant is a themed one. Today, we explore 20 themed bars and restaurants — from a Doctor Who-themed saloon in Brooklyn to a beer spa in Prague — that’ll satisfy the most curious diners! There are even restaurants where you can be served by “ninjas” and by real prison inmates. Let us know which ones you’d actually visit and which ones you’d rather pass on.
