I also just finished completely reworking all the lighting and furnishings in the Decor room at the store with all new pbr textures, as well as adding a few new items. As you enter the lobby, walk straight back to the right and through the Decor doorway.

Important note: if you land on the top of the cinema complex when you first arrive at the Emporium, take a single step forward to activate the teleporter to the lobby.
