Jinju, Korea - Traditional Korean BBQ Dinner at U-Ga-Chon
This is quite simply the best restaurant in Jinju offering "bulgogi" (Korean-style BBQ beef) and "kalbi bulgogi" (large beef-ribs), accompanied by a selection of kimchi and side-dishes like raw squid tentacles & vegetable salads.
Dinner ended with choices of water noodles/ "mul naengmyeon" (물 냉면) and spicy noodles/"bibim naengmyeon" (비빔 냉면).
Desserts were fresh fruits and "shikhye" (fermented malt-rice drink).

If your sister is going to live in Geoje, she'd probably be able to find *much* better options in Busan, which is more "cosmopolitan" than little towns like Jinju or Sacheon. Of course, "cosmopolitan" is a rather relative term here, as even Seoul, by far more exposed to outside/foreign influences, still felt very introverted culturally to me.
