Smoothie King is located on the 2nd floor of the Epicenter, right next door to Breugger's Bagels. They open conveniently at 7am, and the service was prompt and friendly.
The smoothies are waaaaay better than Robeks or Jamba. But like any smoothie place I find it extremely expensive. My 20 ouncer came out to a whopping $5.... I could have gotten a coffee AND a bagel sandwich at Breugger's next door. There are 3 sizes, plenty of smoothie varieties and enhancers (99 cents each). They also sell snacks like cookies, protein bars, Luna Bars (yum!), and banana breads - but they're all marked up and pretty high in calories. For cheap energy bars, go to Trader Joes.
Make sure you order your smoothies without their added sugar and you'll save 100+ calories. I haven't tasted it with the Turbinado, but without the added sugar it tastes plenty sweet.
