Seriously, this place is heaven to someone who just turned 21 or someone trying to not remember the night.
Slushies and Alcohol are usually a plus in my book when separate. But add one to the other, and its like you have entered into some new territory that you never thought you would be.
I would opt to buy one of the refillable cups as they save you a few bucks when you back (BECAUSE i promise you will go back!).
