I initially didn't want to go to a maid cafe but I met up with a fellow couchsurfer for an anime event:
Neon Genesis Evangelion in Ginza, which was awesome if you know what it is all about. Either way we were approached on the street by several different girls in
Akihabara. A cute Japanese girl dressed up in a maid costume spoke to us in broken English about different locations that we could go to. There is a huge market for it in this otaku area since there were so many different brands of maids.
They ranged between different coloured maid costumes and girls that probably do different acts and whatnot. We ended up going to one which was quite small in size. When we arrived we were greeted at the door and then at the table, they do a full introduction at your table and tell you how much your table charge would be. The one we went to was on the 4th floor and was a 500 yen charge per person per hour. From there we had our maid tell us that her name was 'Mew Mew' she did little hand gestures. The cafe itself was all very pink and all the girls talk in this very high pitched voice, maybe some people would think it was cute but for me it was strange and would be very horrible if I was made to talk that way all day. It would have probably give me a massive headache after 15mins.
The customers consisted of single men, couples, foreigners and one large group of salary men. They had huge sundaes for about $8, instead we bought a cute chicken curry teddy bear made out of rice, it wasn't fantastic but we had tonnes of fun eating it. Before we were allowed to eat it we were made to sing a song with the maid that dropped off our food, I assume that because of this table charge they had to entertain as well as be cute.
During this time we were made to put on some animal ears which we did and so did some of the other customers. They did a dance and song and also tried to persuade people to buy a Polaroid for 500yen. They were tiny but very personable since they drew on the photos with markers. I didn't want to pay for a photo but they wouldn't let me take one with my camera. Either way it was an experience but a lot of people would think it is demeaning for the girls that work there. As for myself when one of the new girls started shift she jumped right into action and looked pumped to be at work. Go there and see for yourself.
