This is the coolest and fanciest Walgreens in the world. Built in a historic bank (the Noel State Bank), this Wicker Park Walgreens has a gorgeous ornate ceiling and other historic decorations. Go downstairs and find the Vitamin Vault which is exactly what it sounds like: the old bank vault filled with vitamins. They also have examples in the Vault of old tonics that were sold by Walgreens, plus some old diagrams of the bank. A beautiful, fun location that adds extra meaning to being at the corner of happy and healthy.
