They used to be all over but the ones near my end of Mass. pulled out over six years ago, probably closer to ten.
It is id ZCD in Alpert and Smith's Video Arcade, Pinball, Slot Machine, and Other Amusement Tokens of North America. The Alladin's Castle arcade chain was founded by Chicago businessman Jules Millman in the 1960's. He noted that coin games were mostly in undesirable places such as taverns, and decided to open a chain of family arcades in suburban shopping malls. Bally Mfg. Corp. had bought out Alladin's over 350 arcades. I did not verify this last bit, but I believe that Namco has owned the chain since 1993.
