Do you want to be served by a waiter with a condom on his head? How about by a robot or a monkey?

Eating out can get mundane at times, but a spate of outrageously themed restaurants are providing diners with some very memorable experiences.

While Japan has the most number of weird restaurants, that coincidentally appeal to all sorts of strange fetishes (think waitresses dressed as French maids), there is a growing number of extreme cuisine eateries across the U.S., Asia and elsewhere.

These off-the-wall and eccentric themed restaurants are sure to provide a dining experience you will never forget.
