I tried a Jamba Juice for the first time back when it was Zooka Juice. I thought that place was amazing. Obviously they mostly sell smoothies, but they also sell some snack foods, clothes, hats etc. You can even get a shot of juice made from fresh grass if you want it. The smoothies are very filling, so I was glad when they came out with smaller sizes in some of their more popular drinks. You can always get a free power booster and can customize the drink any way that you want.
