Carolina Smoothies features a wide selection of smoothies bound to fit each person's tastebuds.
I could write a long-winded review about the place, but here is the short summary:
These are healthy, made with fresh or frozen fruit, and great for a post-workout snack. The prices are reasonable (~$4, depending on specific item), and the service is fast and friendly.
The buy ten get one free card is a nice touch. And I Love, Love, LOVE the dark choc. covered almonds.
