Good luck, hopefully you're opening a bar because there is a market demand for a bar and pinball at the location you're looking at and not because you'd personally like to see a barcade in your town.
Make sure you understand the demographics. There are two barcades in Raleigh, only one has partrons overflowing out the door onto the patio, and it's the one with half crap condition pins. The slower one is the one with nice pins, runs tournaments, etc. I know the CoinBox guys keep a big lineup of modern, clean, working games and most of their money comes from casual players in the bowling alley anyway, not people who visited to play pinball.
