Yes, although only at dinner time as far as I know, and with very limited choice (2 or 3) and ok but by Japanese standards a little underwhelming quality. The HND lounge has or had the teppanyaki mini station instead - again, only a couple of choices.

To be honest, as much as I adore flying JL F and J, the lounges are really nothing to write home about food included (and I am a huge, huge, lover of both Japanese food and food in Japan - including non-Japanese), and those lounges are not really the model I would ideally like the CCR to emulate (Incidentally, QF F lounges used to always have raw fish dishes on the menu though it is no longer as systematic, and I must say that they were always very good. Not true sashimi or sushi, but more along the line or "easier" ceviche/crudo/tartare which is already a pretty good start!)
