I also forgot about Natsuge Museum which has a decent selection of old arcade games - like Sasuke Vs Commander.
I can see why the chains have expanded though - generally speaking, there is the issue of a lack of interpersonal relationships and long working hours. It does make me cringe how they have become a tourist attraction in itself though. There are something like over half a dozen Maidreamins in the district alone and the staff are multilingual, and Maidreamin quotes high tripadvisor scores. It’s somehow become an appealing activity to visit for many(?) casual visitors from overseas.
That said, I did visit a boutique/independently-run maid cafe once (the theme wasn’t maids but same idea) and while the food was pretty poor (you’re obviously paying for the company) the other customers weren’t old guys but office workers who looked to be in their late 20s or early 30s, and the waitresses didn’t look miserable. That could of course be an outlier, but they also didn’t have anyone handing out flyers whenever I went by, it was just advertised by a board outside on the ground.
It was still close to the low point of a great trip overall when there are much better options for a meal.
Anyway I digress, this is about how this stuff has come at the expense of game-focused stuff, which is definitely a negative. Just wanted to add my own observations though.
