We were just there for lunch on 7/11 and celebrated my cousins' birthday. It wasn't planned in advance and we didn't have an ADR, but when we mentioned it to our server about the birthday he brought out a piece of chocolate cake and a group of the servers came to our table and sang Happy Birthday in french. The cake was ok - it was a chocolate layer cake with raspberry sauce and was a fairly large piece. Afterward, I saw the same type of cake for sale in the bakery behind the restaurant. I'm sure you could probably order a birthday cake in advance by calling the restaurant.
