I don't think they're always called "arcades", but there seem to be quite a few places to play VR games popping up. I've seen multiple in a few different cities now.

Here's an example of one in Redmond WA, I think there are at least a couple more in Seattle: http://odyssey-vr.com/

Another Seattle one, in my 'hood, still haven't bothered to go.
