The Come-A-Lot Casino on The Strip, Las Venturas, San Andreas.
Come-A-Lot is a large medieval themed casino along The Strip in Las Venturas, based on the Excalibur Hotel and Casino in Las Vegas. The casino is inaccessible, but a horseshoe can be found in the casino's moat.
Come-A-Lot's name is a pun on Camelot, the realm associated with King Arthur, along with Excalibur, thus the origin of the name for both casinos. The name may also be a double entendre of "cum a lot", a sexual phrase referring to excessive ejaculation or orgasm.
