=========
The logo is a real restaurant chain called Matsuya's in Japan. However, as seen above they're very prevalent in the Yakuza series while from my knowledge haven't been in much else game wise. It's possible Namco Bandai just asked for the chain to include in a new Tekken 7 stage, but why go through that effort if not for a new Yakuza stage?
So what do you think? Just a coincidence? Or is is finally happening?
