Callahan's Secret by Robinson, Spider. mass_market edition. ISBN: 9780441090747.

Callahans Place is open for business, and all of the "regulars" are here--a talking dog, an alcoholic vampire, and two telepaths--enhancing their joys by drowning their sorrows. Everyone, that is, but Mickey Finn, a seven-foot tall alien in danger of enslavement at the hands of a traveller from across the galaxy... Come inside, pull up a chair, order a drink, make a toast, and let Spider Robinson introduce you to the most unique patrons to frequent any establishment, at a bar where the most important law is "shared pain is lessened; shared joy is increased." And if theres time left at the end of the night, just maybe theyll save the world...
