Tokyobike Lovefest

Have you guys heard of Tokyobike? They have an outpost in NYC for the summer (it closes August 30) and I am incredibly tempted to run down there and buy a bike. Every day after work the thought crosses my mind. Mostly because they're really cute, but also because...they're really cute. Is $700 a lot for a bike? I feel like it isn't, but I haven't ridden one since college and am pretty well in the dark on these matters. Do we think it'd get stolen? Maybe I'm getting ahead of myself...

The model I most like is the Bisou, which I would get in navy, because navy is the best. NYC has this summer streets thing where they shut down all of the traffic and encourage people to bike, jog, etc., so I it just feels like now is the time to go bike shopping. Thoughts?
