Staff is great, but the store is tiny and awkward.
I love Jamba Juice and I'm so happy there's one so close to my house now. They over ice the drinks sometimes so the consistency of drinks isn't perfect. I dig the differences because the essence of what I order is there.
The store is tiny and if there is more than one person ahead of you, you'll be standing at the door. Not cool. Also, it's Vegas and metal door handles when the 110 degree sun is shining on them is evil. Get some kind of rubbery covering. It won't change much, but it will help.
I love Jamba and will visit here a lot. I've already visited about 10 times since they opened last month.
