I've been to Sakura Tokyo... pretty good "flippy food" (teppanyaki).. though we
felt the chef was new. I had a small selection of sushi, which was very good (I
think I had bincho maguro and a few other things). This was about 3 months ago.
Their website is

Never been to Zipango's.. I don't get out that way much.

Come to think of it.. the last time I had sushi was about 3 weeks ago...
