I took this from another site: "There is an elevator bank on the casino level of Cosmo. It's kind of hidden but if you troll the machines against the north wall, you'll see it in a little alcove. Two elevators. Take them down one level and you will be in an eerie parking lot type place. There's a convenience store there and you can get beverages and snacks, including water, a lot less expensively than the casino gift shops. The convenience store connects this parking lot place to the entrance of the Jockey Club. There's no fancy sign or anything. Just get off the elevator and go to your right and you'll see the door up ahead." Anyone been to this store?
