If your in the area drop by and check it out. Its a 4 player version. It also has a wicked sound system with a powerful subwoofer.
This is the arcades official website as well: http://gamegridarcade.com/
The owner is nice guy and I'm sure he would answer any questions anybody has about the game. Lots of classics in there like a Crystal Castles cab. Also some pins.
Only 50 cents a play its a fairly good bargain play. Here are some pics of the cab that a fellow shmup player took from his cell:
