Mary's place is the name of the fictional
bar that was built to replace that other great fictional
bar,
Callahan's place.
Spider Robinson uses Mary's place as the setting in his books
The Callahan's Touch, and
Callahan's Legacy. In the series, Mary's place is built by
Jake Stonebender after the original
Callahan's place is destroyed to save the world, and
Mike Callahan goes back from when he came. Much like
Callahan's place, the main activities at Mary's place are drinking, punning, and saving the world.
