The smoothies aren't necessarily the best but definitely better for you than Jamba Juice. The 3 stars is more towards service as I've been here several times and the only thing consistent is its inconsistency. I've had to repeat my order several times and when driving up the window, they don't have everything prepared.
I admit I'm not the most patient person but drive-thru service should not be more than 10 minutes for one drink. But like all other "fast-service" joints, there are always hiccups so I choose to give them the benefit of the doubt. And hey, I'm still going back aren't I?
