Okay here's the thing about Fat Tuesday. You get a giant margarita or other alcoholic slushee, in a souvenir cup, to lug around with you as you spend hours walking around the strip realizing its WAY bigger than it looked on tv. Everyone has to get a fat tuesday drink at least once while in town, I think it's actually a law. When it's like 90 degrees in the middle of the desert, there's really nothing better. I came to Vegas for my 21st, and this was the first thing I drank (illegally at least, I didn't get carded at the comedy club a few hours earlier...) They also have jello shots, but just say NO. They taste like cherry cough syrup that has been lit on fire. Needless to say I felt so sick the next day.
And for the reviewers who are complaning about how only annoying tourists get drinks from here, well YEAH. It's LAS VEGAS. It's a TOURIST TOWN. If you don't want to deal with annoying tourists who are excited they don't have to abide by an open container law, then MOVE. Duh.
