Honestly I think it comes down to the location and their setup. Do they have other games/activities like a pool table, darts, shuffle board, arcade game, etc? I've found that places that have other activities leads people to actually move around and engage instead of just hunkering down at their table and throwing back beers. I don't think that one loan pin would be an issue especially if its in a trendy place.
I have one pin (TSPP) on route right now at a brewery that's doing really well. There is another pin there (walking dead) along with board games, a cocktail arcade game, etc. I will say, if your location caters to families I'd recommend a less scary theme like Star Wars or Guardians as I've seen parents dump quarters into my pin as TWD scares little kids. Just my two cents, good luck!!
