Forget those cooler-than-thou chain spots: Rocky Mountain Fruit Shake knows how to make a liquid lunch a stirring experience. Fresh fruits and juices mix with frozen yogurt or ice for healthy, refreshing shakes; for an extra boost, add protein powder, ginseng, lecithin or spirulina. Take the invigorating brew back to the office or sit in the food court where you can feel truly comforted by the fact that your life is less miserable than those of the lonely souls who hang out here. And if your day has been so tough that even that doesn't help, the only option is one of their dreamy floats, which add a big blob of creamy frozen yogurt to the top of the glass.
