I went to this amazing arcade that opened up in Hicksville called Round 1 - it's basically like a weeaboo Dave and Busters. So many great Japanese arcade games there, my favorite being one from Square-Enix (!!!) called Gunslinger. You dual wield pistols and can attach them or stack them because they both have magnets on them. The tutorial is more complicated than most console games and actually costs money just to play through! Game overall is really fun though, it's an arena battler type game.
They also had a bunch of great rhythm games (Theatrhythm, Project Diva, some Capcom rhythm game), some fighters, a really old Namco game where you play as some undead samurai and fight youkai in 3 modes (platformer, side scrolling beat em up, and overhead hack and slash). They had the new Daytona, which just seemed to be a graphic overhaul of all the Daytona 1 and 2 courses, the new Cruisin which is simplistic fun. And they had Music Gun Gun 2, my favorite light gun/rhythm hybrid from Taito. Plus there were so many hot Asian girls walking around which made things even better.
