Some restaurants hire only robots to serve their customers and perhaps some hire only fearsome, yet honorable, samurai to bring out the munchies. However, it turns out only one features actual robot samurai working the floor.
A Japanese restaurant in Thailand called Hajime is staffed by a bunch of, well, robot samurai. Essentially they are just robots dressed as samurai because it’s really difficult to program a code of honor into a robot. As a matter of fact, there are sheets of glass between the customers and the samu-bots which is something Japanese nobility never needed.
If you go you should order a ham on rye from the samurai. That would be funny. Sword of.
