PDX: Syun Izakaya Japanese Restaurant and Sake Club
Yes. There should be several threads. I don't think it's as good as Biwa, though they have some different emphases. I don't think their sushi is as good as Hakatamon or Mio, either, and definitely worse than Murata or Hiroshi. A friend went there fairly recently and he always loved them and thought they had taken a serious nosedive in quality. You might want to look at Yuzu if you're on the west side. I haven't been there yet, but people on PortlandFood.org seem to like it.
