I've been on an unsuccessful quest for good chirashi in Arizona since the great Sushi 10 in Tucson went under (it's still there, but in name only - bought out).
I went to Shimogamo in Chandler the other day, based on the review below (re Google forum). Chirashi - $20 - too much, mediocre and not worth it . Lots of bowing and thank you's ain't worth the extra bucks either. Few customers at lunch time. I kinda agree with that bad recent newspaper review (badly written review, too).
I also tried Takamatsu on E Speedway in Tucson. It's one of those semi-bizarre Tucson oriental places - like 17th Street Market (which has now weirdly morphed into a combination Asian-European-food and guitar store market - sometimes things seem to be getting surreal!), and that Tucson Chinese market with all the giant monstor urns, like something out of a nightmare!
Takamatsu has bizarre service, like other reviewers have noted - and sometimes no service at all - but the Korean food section - - it's divided into 3
sections - Korean, Japanese, and Mongolian bar bq - - is actually very good - much better than the little old Korean restaurant a bit farther west on Speedway. The Japanese section is totally mediocre and seems
to do most of its business selling all you can eat California rolls to military people from the air base (10% discount for active or retired
military). The chirashi tasted like a flattened out California roll or something.
The third mediocre sushi joint I tried is Sachiko on Ft Lowell in Tucson which I kept in mind because someone here (Google forum) recommended it a couple of years ago. Mediocre chirashi and $1.50 extra for a little
glass of hot tea.
P.S. The two owners of S10 are reportedly planning to open up new restaurants in Tucson and Chandler.
