Good place to get cheap liquor when you feel like you are being ripped off by Mandalay Bay. You are still gettin ripped off here, but it's not as much as getting drinks made for you one at a time.
A bottle of tequila will cost you $21 plus tax (8 oz?). $10 plus tax for margarita mix. It lasted 4 days. Of course, I wasn't getting drunk which I didn't want, but if you buy drinks elsewhere you pay $15 a pop. If they were good that would be worth it, but I can make better. Candy and other goodies here too. Just off the elevators.
