When I first moved to Coolidge Corner four years ago, Dok Bua was a grocery store with a lunch counter, stools, and three tables by the window. I started eating there regularly. Then I discovered Chowhounds and I (and others) started talking about it. The rest is history. I stopped by Saturday night at about 8:30 and the place (now a good size restaurant) was packed. I usually go during off hours on weeknights. I asked about it being this busy and they said that that's the way it is. In fact they were taking reservations for Mother's day. Ah, the power of the internet and Chowhound.com.
