A Vegas classic - a great place to start, because if you come here at the end of your night it's gonna be a bad time. The extra $1 shots are definitely worth it, but even more than that is having a flask of rum nearby so you can add your own (I'm such a skeptic that I figured they watered the booze down...I could also just be an alcoholic).
Pretty much all of the flavors are delicious...it's 100% sugar, what do you expect? Peach, mango, pina colada, strawberry, orange, there's pretty much something for everyone. Keep the cup and return for cheaper refills during your time in Vegas. Compared to the $$$ you'll drop in the bars, $10-$20 isn't a bad place to start for a fun drink you'll always remember.
Already looking forward to next time! :-)
