DuBois's/Deschamps's

DuBois's or Deschamp's, depending on who you ask, is the unofficial name of the gambling salon run by Pierre DuBois and Adelaide Deschamps. While the salon does not have an official name, as it's run from the ground floor of the Hotel de Mademoiselle Deschamps, some call it DuBois's or Deschamp's. One could call it DuBois's due to the fact that Pierre DuBois is the one who actually runs the salon or Deschamps as her presence is a big part of what drives traffic to the salon in the first place.
