Mitsuwa has been advertising a Rice Fair from today until Sunday, so I went tonight to check it out. It's basically one of the retail food booths that they usually have during fairs (didn't spend much time there), and an Omusubi booth set up in that temp kitchen area next to the sushi.
I don't profess to know much about omusubi (I prefer yaki onigiri), but enjoyed the one that I had with ume. The rice was fairly separated with a little salt, and while not hot, it was obvious that it hadn't been chilled--ever--and the texture benefited from that. The omusubi ranged in price from $1.80 to around $3 for more elaborate ones like shrimp tempura and unagi. They also had something called ... benkura? benkaru? that I know nothing about.
There is a "Customer Appreciation" event going on through the 16th. Every permanent stall has a special. Santouka has a 20/day "Seafood and Vegetable Tonkatsu Ramen"
I'm fairly enamored of Santouka's ikura and salmon with rice lately -- it's not as amazing as the guest ramen chef who sometimes comes to Mitsuwa, but it's kind of perfection as a comfort dish.
The stall that had the decent tonkatsu -- North side of the food court, first booth if you walked in from the north entrance -- has permanently closed. I went in tonight hoping that the booth had been taken over by a guest for the Rice Festival, but to no avail.
