different beer at sushi places....OB Beer?

My girlfriend and I frequent the Korea House and discovered that we really like OB, a korean beer. The owner told me last week that he was out and the stock he had was given as a gift. We went to the new Korean market on North Lamar but they do not sell alcohol. Grapevine used to carry it but not anymore and I have not seen it anywhere else.

Does anyone know of a market that carries OB in Austin?

Thanks,
Kirk
