I fear this'll probably be a custom drawn logo. Let's wait and see if anybody knows this baby.

I may be wrong, but the way the letters in Beau-soir look reminds me of what happens when you start playing with outline points in Illustrator. I would guess at least part of it started out as a square sans like Europa Grotesque that has been flattened. Maybe something squarer, but you get the idea.
