The main arcade on Edgewood ("Joystick") is super popular, but only has 8 or so machines. They're not in good shape either. People want to play, but it's too crowded.
The similar "adult dog park / bar" concept has been absolutely exploding. "Fetch" bar started just across the street from me a few years ago and they've since expanded to over ten locations in three different states. It's huge. And it's always packed to the brim with over a hundred people.
Plus you get to charge membership fees per dog in a subscription model.
People want to drink and bring their dogs.
If the west coast doesn't already have this, get on it. I can't imagine there's much moat apart from branding, but it's got huge growth opportunity.
