nice, thank you both, my bosintang guides :-)
If I undersand well, the "restaurant" kind of places serves only two portions and more (it means hwanggu and 서울 보신탕맛집 30년전통 옛날사철탕삼계탕♬ as well) and I can only use the "market" places, which seem to be "Tong il-ok (통일옥)" or "something outside of the Gwangjang Market", am I true?
