It's expensive/overpriced, but fun. You can sample as many of the adult slushie flavors as you like. And some are quite tasty. You pick out your container, and then get let in behind the fence to mix and match and fill your container. I got pretty creative with this and wound up with a most tasty and delightful frozen drink. There's also no -alcoholic flavors for the kiddos and non-drinkers. They also have a lunch card where you can earn a free refill. If nothing else, stop by and enjoy some free samples.
