Mitsuwa is currently having an "ekiben" fair at its locations in southern California. This is a selection of the various bento boxes that train stations sell in Japan. Each train stop creates a unique bento combination to sell to the passengers (usually through the windows).
The fair starts at 11am and goes on through this weekend (according to my flyer). I just purchased a few boxes (mostly $10 range) though I haven't tried them yet. I am a sucker for their packaging, which the ladies there were keen to pick up. Out-of-control CUTE. The first bento I got is a clay bowl of a cheruby asian dude, containing uni, veggies, pickles, a maraschino cherry and rice. The second one is a clam shell shaped clay bowl containing clams, pickles and rice. The last one I got was a small wooden box of ikameshi. My informant promised the squid are gravid.
There are more combinations with different colors everywhere. Difficult choices to make, but I assure the detail-oriented shopper, a lot of fun.
