I cannot take credit for these -- I think they were both cooked up by my friend Aaron, who has many, many more up his sleeve that I cannot remember now. They're not *exactly* theme restaurants in the same sense that all those SOMA places are/were (a beauty shop! An airplane cabin!), but I like them anyway.

1) The restaurant where the floor is so clean you can eat off it -- and you do.

2) The All Liquid restaurant. Again, no waiters, only clear piping and spigots at your table. Bill is calculated by meter.
