My favorite Fat Tuesday! The only one I know of that still serves mudslides (the best!)
It's in the back of the Forum Shops at Caesar's Palace. At this one, there are actual tables to sit at, and you can watch the show every hour in the middle of the mall (still have no idea what it's about, but I saw fires and sorcery and stuff). You can also get snacks here, at the Chippery, for a salty/sweet treat with your drink.
The only downsides to this location are that shots are $2 each instead of one, and they only carry double-size jello shots for double the price as well. It's also wayyyyyyy in the back of the mall and quite a journey to get there.
You're not really in Vegas unless you're holding a 32oz. yard with extra shots. Come here first!
