I have friends who love Jamba Juice, so I found myself here from time to time during my bachelors. It's not my first pick. I tried multiple drinks here hoping to find one I liked, they weren't very appealing to me. Too sweet, sour, off tasting, etc., etc. It's not you, it's me. My taste buds just do not mix with your smoothies.
The service is friendly enough. I just never seemed satisfied with the product. With the steep price tag, I expected something more I guess. I did have fun trying some of the more unique menu items like your grass shots.
