story identification: fantasy novel with a faun named benji

Trying to track down a novel my father read. (Unfortunately I never read it).

He remembers that the story is being retold by a barkeeper/innkeeper. The barkeeper is retelling some of his life's adventures to someone else who is writing it down.

The main character had a friend who was a faun. I believe his name wad Benji. At the end of the book, thd main character says something like, "I want my Benji back."

I know it isn't much to go on, but any help is appreciated.
