Awful.  The McDonald's of smoothie chains.  The smoothies are terrible. I have no idea how places that continually serve a substandard product get popular.  I can only assume that it is marketing.  I know that a lot of Chicago kids like Jamba Juice because that is all they have ever heard of, but yuck is yuck and boring is boring.  I didn't try one smoothie and quit.  I tried several times to give the place a chance. Terrible. It's only saving grace is the carrot juice.
