Callahan's Place is run by Mike Callahan. The regulars are welcoming and willing to listen to any visitor's problems, no matter how strange, but do not snoop if a visitor is unwilling to share. Strange and unusual events and visitors turn up with frequency in the stories. Regulars at Callahan's include a talking dog, several extraterrestrials and time travelers, an ethical vampire, a couple of Irish mythological beings, and an obscenity-spewing parrot.
A good place for Sam and Dean to blow off some steam and throw some glasses into the fireplace. Bonus points for Sam and Dean's reactions to real live aliens, and to the vampire designated driver.
I hope I got this right. I looked at the other plot bunny offerings before I posted this.
