Absolutely love love love Tropical Smoothie! WIth this particular location, it being open 24 hours is a definite plus.
My usual: a chicken pesto and a Peaches N' Silk (Peaches, Strawberries, and Bananas). Trying the chicken pesto is an absolute MUST! I fell in love and get it whenever I'm back in town. The Peaches N' Silk is a great smoothie if you're looking for something fruity.
If you're looking for an occasional "indulgent" smoothie, I recommend the beach bum (strawberries, bananas and chocolate). It's a nice balance of everything that's included.
Minus 1 star for this this particular location only because the last couple of times I've gone, the employees just don't seem very happy to be there! And that's fine, but it unfortunately translated in a slopping chicken pesto. :( But of course it was still good!
