Arcades still exist, but they have evolved from their traditional roots.
Classic arcades are fairly rare to find nowadays that are open to everybody. You can find arcades at "Family Fun Centers" & Chuck E. Cheeses, but they're geared towards younger children... making it a bit awkward for teenagers (16+) & adults to visit on their own.
The current trend (& the arcade's evolution) is the "Barcade Scene", where a bar is decked out with arcade games. Clientele is generally more adult, but some places will allow some children with some restriction. Dave & Buster's are the most common, being a "family friendly" establishment.
The one place that I occasionally visit (they've been open for 16 months & seems to be doing well) is generally open over the weekend & doesn't allow anybody under 10 from visiting, so you don't have to worry about the elementary brats from potentially damaging the machines (only drunken idiots). They have a small non-alcoholic menu (as I don't drink by choice... & I have a lengthy drive) & some screens with a mix of sports & e-sports as well as a movie in their "chill zone" (a quieter part of the place, with a couple of couches & a fewer "low key" games). Game prices are reasonable being $0.25 for most games. Premium games & Pinball are $0.50.
If do you a search for barcades in your area (better in metro areas. You might have to expand your range for more rural areas), you'll likely find a few places the check out.
Hope this sheds some light on the subject.
