Auraak
2-level Enchantment (ritual)
Any closed door you touch becomes a portal to an illegal underground bar. The bar is always the same bar with the same barkeep. Everyone can come and go as they please, and any attempt to follow them out of the door fails without magical means. Everyone in the bar knows they inhabit a magical bar, and everyone presumably has this spell. The barkeep can sell food and beverages. Any fighting done within the bar is frowned upon. Exiting the door results in coming out of the door in the same place you cast the spell. If someone opens the door from the other (nonmagical) side, they do not appear in the bar. Additionally, if you exit the bar while someone uses the original door, you will be sent to the astral plane for 2 minutes as punishment for not knocking first.
