I love Tropical Smoothie Cafe, especially the one on LVB.  Go during the day and a nice older man actually stands at the door, opening it for people coming and going.  Customer service right at the door.  The counter staff have always been polite.  I even once got a free smoothie just because.  I usually get either the Hawaiian Breeze or Orange Passion smoothies.  The only gripe I have is that it can take a while, but it's worth the wait.  A great treat especially during these hot summers.  Expect to pay close to five bucks for a smoothie.  They also have a substantial food menu.  Get a sandwich or wrap or even just a cookie if you want a snack.  Oh, and this location also recently went 24-hours.  I should stop by after work one of these nights.
