Japan is expensive. Tokyo and Osaka consistently rank among the most expensive cities in the world. With the strong yen, Japan is even pricier for foreign visitors. It's no steal for nerds, either. It's highway robbery.
Geek mecca Akihabara has a bevy of maid cafes to tempt otaku with cutesy food. Popular dishes include "rice omelets" or "hot cakes", which are usually somewhere between ¥700 to ¥1,000 (US$9 to $13) at Akihabara maid cafes—well, ones staffed by dudes dressed as anime chicks. At normal restaurants, you can get a rice omelet—which is rice, eggs, and ketchup—for around ¥500 ($6.50)
