Las Vegas has large slushie drinks everywhere. But this place (like everywhere here) makes it an experience.
You pick out your glass first and they have a ton to choose from. Once you buy (my friends bought me a 100 oz since I'm getting married soon... Thanks...) you get to go in the back where they have 20+ flavors and fill up what you just purchased. Not only that but you get unlimited free samples (I filled myself up almost just doing this). Some were horrible and some were great and some only good if you mixed them.
My friends (thanks again) also bought liquor shots for me and knowing I was the bachelor she was not conservative with her pours.
The customer service was great. She was friendly and even though only two of us bought drinks, she let all five in our group back for samples so that was cool.
I will say (thank god) the drinks are fairly weak because I was okay (read not sick or hungover) after almost (I couldn't finish) 100 oz of slushie and she DID pour extra shots in it.
Fun experience though for reasonable money. Also a good way to spend a hot day hanging out.
