SoSoBa was so so. Maybe I'm too much of a traditionalist but it just didn't work for me (or my wife). SoSoBa has non-traditional ingredient combinations - which is not necessarily bad.
The ingredients were all of good to high quality. The flavor combinations just weren't that appealing. I had the Tantanmen (I can't remember what my wife had). We had takeout so I can't comment on the service. Inside was nicely decorated.
