Time Out says
Sneak a peek inside the first butler's café in Japan, opened in 2006 and functioning as a kind of fantasy world – at least for those who fantasise about being served tea by a gentle butler. Advance bookings are necessary, but even if you can't get a table, stop by the gift shop where you'll still get a feel for the atmosphere.
Showa Bldg B1F, 3-12-12 Higashi-Ikebukuro, Toshima-ku
