One of my favorite spots was the bar in "Fellini's #9", a restaurant (and mostly a bar) near my hotel. The food wasn't bad, and the walls were covered in posters from all Fellini's films, but the best thing was the music. Heard lots of good musicians there, including "88 Keys" Wilson, and his quartet. He and the sax player Roland Young had been playing together since 1954.
The best medicine for being on location with no real company is a sketchbook.
