From Aug. 1 to 31, 2012, Animate Cafe offers special menus in collaboration with Crypton.
I've found an error in the latter page. Meiko's Recommendation is not "Berries with Sparkling Water", it's "Sparkling Liquor with Berries". You see a warning under the photo of the drink saying "Alcohol can be ordered only by adults". Remember Meiko is considered as a heavy drinker by Japanese fans! ^_^
Animate Cafe is located in Ikebukuro area of Tokyo. I lived near the area long ago, but I'm now far from Tokyo. orz
Since the cafe will be crowded during this period, you must reserve a table by lottery.
