What's something you wish would "come back" but you feel like you're the only one that cares?
Couple of things for me.
One is tiny croutons. I don't see them anywhere anymore. They taste the same but it's kind of a pain sometimes to keep the big ones on your fork. The small ones were a little more satisfying to snack on too.
Second is Blue Nehi. Never met anyone else that's tried or heard of it. Damn it was good though. Big Blue is kinda similar but those always taste under carbonated.
I don't know how to explain it, but classic Pizza Hut. Going to Pizza Hut with the family was always great sir down experience and there was usual a small arcade. The pizza was way better than the comparatively tasteless junk they serve now.
Also, arcades. I'm not talking about the "arcades" now we're you tap a card so you can spend a few bucks for some shit experience. It'd be really cool if there was like a millionaire out there that was just an nostalgic and open up a classic arcade, with actual quarter machines. Probably wouldn't make money (probably would be a loss) but it would be an experience I think many would welcome back and would be brand new to a whole new generation of people.
Adding in some things as some people have made recommendations
Cidercade - Texas (multiple locations). Pizza is described as divine!
Im in my 40s and certainly remember the dine-in pizza huts and arcades. There were three in my area, all 3 were in shopping malls. Some of the games were starting to be 50¢ though, like After Burner which moved as you sat in it.
Where do you live? Theres an arcade in the city I live in now (its a bar-cade) but they have dozens of old cabinets and pinball tables. Theyre €1 per play, though..
Closest you can get to that experience that I know of is the Pinball Hall of Fame in Las Vegas. They got all kinds of machines, old and new, that only take quarters. Isn't just pinball machines either, they got a sizeable amount of arcade cabinets.
