I've tried the other soda shops in the area, and while they're alright, The Fiiz really stands out. The drinks are quite good (my personal favorites are the Chandler Bing and the Yowza), and the other menu items are extremely enjoyable (I'm developing a root beer float cupcake addiction).
But what sets the place apart is its superior customer service and really fun decor. Makes it a great place to hang out at with friends.
