If you're looking for a tasty smoothie, this might be a good option if you don't mind syrups and sherbet style smoothies. I do believe they add some frozen fruit, however I noticed they use some syrups, juices and sherbets, as well. I prefer fresh or frozen fruit and maybe ice and almond milk, Tropical Smoothie seems to be more sugar heavy. For just under $5 you get a pretty big smoothie, like 24 oz I believe.
The place is clean, service friendly, and I like that they donate to children's charity.
