The name is Charles Wetterling and Sons. Pretty sure it's a wholesale butcher. The phone message didn't really seem to say "we're open to the public", however.
It's on a stretch of George St. that used to be rather industrial and next to an old club that I can't remember the name of but as of about 6-7 yrs ago, is filled with multimillion dollar homes. I'm surprised it's still at that address. Google maps plants it right smack dab in the middle of them.
