Movie theaters (the cineplex kind that also show major first-run Hollywood movies, not just arthouse ones) in the US already show live events (particularly art events -- live theater and other performances -- but I think there has been some sport events, as well), and there are several (including at least one chain) that have full menues, including alcohol, for at-seat service.

So what you are saying needs to happen already is happening.
