New sketchbook theme, as promised. These are restaurant names I found in a 1966 edition of the National Restaurant Association member directory. The Association still exists, but no longer publishes a list of members.
Dante’s Furnace seems to be long gone. The only evidence I was able to find of its existence was this 2-sentence observation  from a 1964 New Yorker article.
As for the artist on this one: I’m not sure. All I remember is that I met him that same day, and he was pretty excited about getting to make a literary reference.
