Agreed with above comments. Check for zoning issues and tax requirements but if you can get past that stuff why not give it a try.

We have a barber shop in town that has a pool table in it that looks like a cool place and is always busy. I have a regular barber I have been using for years so I have never been in the place but they seem to be doing everything right judging by the number of people I typically see inside. People like to keep busy so why not a small arcade while they are waiting or after they are finished?
