No Vegas trip is ever complete without getting a drink from Fat Tuesdays at least ONCE. It's simply the best alcoholic slushy ever. Picture an Icee but with tropical flavors and way better.
Combinations I've tried and loved: mango & strawberry, strawberry & pina colada, and peach & mango.
You can also save a few bucks if you purchase one of their reusable containers and bring it on your next Vegas trip. ;]
