Callahan's? Nah, its in NY, at least according to Spider Robinson, who created the place. Good luck in finding it though, outside of the regulars, the only folks who seem to find it are those who actually need to find it, outside of the occaisonal odd time traveller, extraterrestrial or alternate planar denizen (whom from time to time are actually of the category listed above, those who need the place).
See "Callahan's Cross-Time Saloon", or "Time Travellers Strictly Cash" for further details, and remember "pain shared, is pain decreased, while joy shared is joy increased"...

Not any more. Moved lock, stock, and patrons to the Florida Keys.
Spider Robinson's output of fiction seems to have dropped to almost nothing lately. The mary-jane must finally have rotted his brain.
Until it got blown up with a pony nuke.
The new place is in the keys, named "The Place because It's Time"
Lordy I am such a geek. :-)
