I have been coming to Jamba Juice for years and always get the same thing: a power sized Orange-A-Peel and a apple cinnamon pretzel. Starbucks & McDonalds cannot compete with Jamba (although Tropical Smoothie Cafe gives them a run for their money on price point).
The ingredients are fresh and the staff is very vocal and friendly. The best part is how satisfied I feel after having a smoothie from here, not to full and yet full of energy!
I remember being sick one time and how good it felt to get the "Cold-buster" in a few days I was good as new! (Please seek a doctor for serious medical issues however ;) )
