We made reservation at Kani Douraku かに道楽 道頓堀中店 the night before and we were 30mins late as we went to Osaka Castle prior. We were so glad that they were still keeping the room (yes, we got a room!) though I didn’t call them about the delay.
They have some lunch sets which are around half the price of their dinner menu. And to my surprise they also have kids meal!
There is crab hot pot rice in the set but since it needs 40mins to cook and we have a plane to catch, so we switched to crab sushi instead.
