Dr. Facileir's Voodoo Emporium is a dark establishment of the villainous Doctor Facilier in The Princess and the Frog. It's the location of the doctor's voodoo magic, inhabited with hoodoo and the spirits from the other side.
Whether or not Facilier resides here, or merely uses the place as his basis for black magic is unknown. However, it is made clear that his friends of the other side reside there.
