Came here today after I saw my holly grail of signs on the corner while walking to brunch "kombucha on tap" I was stoked!
They have 3 flavors on tap, I went with the rosemary lemon. It was very good. They make them with honey rather than sugar and you can really taste the honey and while it still has carbonation it was less acidic which I enjoyed. My mom got the strawberry smooth and she said it was really good, lots of flavor and good texture.
Most of all what stood out here was the service. The guy working( possibly the owner? Long dreads) was an awesome friendly guy. Super laid back friendly vibe. He was even giving me pointers when I told him I've been wanting to make my own kombucha at home. He seemed like he just got back from a relaxing spiritual vacation in Bali or something because he was just very calm and soothing while still upbeat and friendly. This guys service really makes this place stand out. Will definitely return when in Phoenix!
