Fat Tuesday might just be my favorite thing in Vegas. We first encountered this location which is at the end of the Forum Shops in Caesars Palace surrounding the Atlantis show fountain. It was 10:30 in the morning but day drinking is more than acceptable here. There are about 85 different drink sizes here to ponder (mild exaggeration) and I felt like a kid in a candy store with wide eyes and my head tilted back taking in everything. We settled on one of the normal looking tumblers (but not the smallest size) which if you bring it back, you get a cheaper refill. And you will bring it back! We sampled a few flavors and I got margarita, the bf got 190 octane. We were tipsy by the time the Atlantis fountain started, which was probably a good thing. This Fat Tuesday's has a little seating area if you need to take a load off to enjoy your adult beverage. They also have test tube shots, jello shots and who knows what else!
