Anyway! Those spoilsports at Eater had to actually go get the answer from the man himself. As they reported:
[H]e reports it stands for Date of Birth. Those little ones between the letters represent his d.o.b., November 1 (see also: Bao 111). When the restaurant opens it will serve French Vietnamese fare with breakfast and brunch offered all day. There will be a dinner menu, a late night menu, and a $29 prix fixe. His friend and onetime business partner Pichet Ong is in charge of dessert.
