First the bad news. I've confirmed that the Columbia branch of Bangkok Garden has been sold. I went to the Bethesda location for dinner this evening and spoke with the owners. I was told that the new owners of the Columbia location are Tarin Thai, (not Tara Thai- sorry about that), out of Virginia. According to the previous owners, the new owners have been granted the right to use the Bangkok Garden name for about 6 months; after that time, they will have to change the restaurant's name.
Now for the good news. Bethesda isn't that far away. . . .Anyone know more details? I see a reference to a Tarin Thai on Yelp, but that Herndon restaurant is described as closed. When people were reviewing, they focused on a Thai buffet. Thanks to Vida for the update.
