Technically smoking is allowed in restaurants in Japan. In practice we haven't seen it much. Not in Kura though. When some people smoke they chain smoke. Pain in the arse. Thankfully it was only one person. Obviously pregnant Michelle was really impressed (see photo below).
Otherwise we had some excellent sashimi, sushi and tempura. I've seen some horrible reviews on TripAdvisor for Kura but on the whole we thought it was pretty good. I think we found Kura in the Lonely Planet or Rough Guide.
