the arcade I grew up next to was like that, they sold hotdogs and nachos. I'd have pool, air hockey, and foose ball. a few pinball machines, 2 or 3 four slot neo geo cabs. load em up with metal slug and SNK fighters. a nice mix of beat em ups, and shooters. a few mame cabs for the older stuff. the newest fighters would have to have 2 to 4 cabs each, set up for tournament play. I'd slap a old style juke box in there and some big screens. have football on sundays, ufc events, boxing whatever. it's really too bad that the arcade is dead in most of the world.
