This sounds fun: The ROBO CAFE [jp→en] has just opened up in Osaka, Japan, where customers can watch Nuvo dance, view a Segway of course have their crumbs cleaned by a Roomba. Sounds like a perfect place to unwind after a day at the wearable-computing conference I’ll be attending there in a couple of weeks :).
My Japanese is non-existant and Google’s isn’t much better, but here are links to a map and more details here [jp→en] and here [jp→en].
