So, I was living in the Osaka area for a while a few years ago. I'm coming back for a visit in a few weeks and I'm hoping to find the site of a very tasty meal. I was taken by my Kyoto-ite boyfriend to an amazing tonkatsu restaurant which would have been in the Kawaramachi area (it might have been on a corner, possibly close to Takashimaya). It was very modern inside: lots of shiny black surfaces and bare wood, plus the sleekest washrooms I had seen in Japan. I think they only served tonkatsu. On the tables were little mortars and pestles for grinding up sesame seeds exactly to taste. Anyone have a clue where I'm talking about? Unfortunately I can't ask the guy who took me there as we are no longer in touch.
