As a customer of this particular Jamba Juice for as long as it has been around I can say that its a great place to go for a fruit smoothie. The drinks they make are pretty consistent, but occassionally your favorite drink won't taste as awesome as it usually does, but this is a problem at any juice-store. The customer service at this location is very good, whether you come early in the morning or late at night. It is usually staffed by young college-student types. The only downside here is that due to the location there is usually a bit of a wait in line, and if they are busy your drink can take a while (less than 4 or 5 minutes, usually).
They have an assortment of other products for sale as well as drinks. You can get your own juicers and recipe books, water bottles and stuff like that. There are also T-shirts, license plate frames and bike jerseys. I just bought a bike-jersey here and it is of very good quality and the price was fair.
