Looks like you have a Nektar Juice Bar! I go to the one in Rancho Santa Margarita when I'm home in California! They are amazing. You can also work with them to create a menu and how long you want it to last. They'll have ready for you to pick up daily!
I've done the 3 day Jus by Julie cleanse a few times over the past few years. I really enjoyed the taste and never felt tired or jittery. It's delivered in a reusable freezer bag which is cool too!
