The Summer of 2011 seems to be the summer of the popup. All over the city, we have people "popping up", providing what the public never knew they needed, albeit in short stints. From lobster rolls and good old American barbecue, to cocktails on the roof of a car park to green lakes, they are all there as long as you look for them. I'm a big fan of this kind of experience, it keeps things interesting, and interesting is definitely what I got from two recent Japanese themed outings.
