Maid Kissa are a new phenomemom in Tokyo. "Kissa" is short for "kisaten" in Japanese which means Japanese. They are mostly found in the Akihabara area of Tokyo.
Maid-kissa are coffee shops where the waitresses where fantasy like maid costumes. They dress up to look like characters from famous anime or Japanese comics. Since Akihabara caters not only to electronic enthusiasts but also young Japanese otaku which translates roughly to nerd in English.
On Sundays down Chuo-Dori, the main street in Akihabara you can find the "maids" passing out pamphlets to their shops to passers by.
Definitely a unique Tokyo experience!
