Fat Tuesday's is one of the things I look forward to everytime I come to Vegas. I love smoothies such as Strawberry Daquiris and Pina Coladas. Fat Tuesday offers a wide variety of fruit smoothies with alcohol in it, and they are all delicious! The price varies by the size you get. You can get sizes anywhere from a normal 16 oz cup, into a yard long cup. Also, if you want to add extra shots to it, they're priced around $1.00 each.
Just a couple of days ago, I was here and had a mix of the Strawberry Daquiri and Mango Daquiri with 4 extra shots of rum... mMmM delicious. The best thing is, it tastes great, gets you buzzed while you're walking around Caesar's. :-)
Watch out though, it does make you feel very bloated, but it's worth it!
