Great locations and super friendly employees. I come here at least once a week and the service and quality are always awesome. I've been here when it's slow and when it's busy. Either time, I feel I get my order in a timely fashion. Usually when it's slow I'll make conversation with one of the employees and feel really welcomed.
I say it's a must to be on their emailing list. I was able to cash in on a BOGO they were offering for a 3 day period less than a month ago. So if you are someone who frequents a Jamba Juice often, consider signing up. They let you know of any deals, new locations, or a new product you may not know about.
Overall great customer service, great product, and I could not ask for much more than that. They will definitely continue to get my service.
