I think perhaps that I also would not choose the Prancing Pony as a spot to relax with a couple of beers. But, aside from that,even though the inn was presented somewhat differently by Jackson than by Tolkien, I liked the movie version of the Prancing Pony alot. I thought the imagery was beautiful, many of the scenes there could have been taken right out of a Breughel painting (I saw where a movie reviewer thought this, but even so, it's true).
I also read on TORN or somewhere that every drinking vessel and utensil in the movie (which would include those in the inn) were designed and made from scratch, to make sure nothing looked remotely modern. The whole idea of this is fascinating, Jackson's commitment to (every detail of) the movie was unbelievably 100%+.
Butterbur didn't introduce anyone except Strider and only after Frodo asked about him
