Love numb! This is a ritual for me in Vegas. Order the 2 smaller cups and bring them back for discount refills. I love the Margarita with an extra shot. The bartenders are nice and cool. They'll even rinse your cup so you can put it in your purse clean for later! They even mix and match flavors if you want something unique (mango margarita, yum!). I always walk to Caesars Palace, grab a numb, eat at Gordon Ramsay's, then head to the poker room. Watch out for brain freeze, though. Best tasting of the frozen drink bars by far!
