1. The 3 Essential Magic Phrases
1. "Jeo-gi-yo!" (저기요!): Meaning "Over here!" or "Excuse me!". Never be shy; in Korea, raising your hand and calling out politely is standard etiquette if there is no call button.
2. "~In-bun ju-se-yo" (~인분 주세요): Specifying portions. In barbecue spots, meat is ordered by portions: "Samgyeopsal i-inbun juseyo" (2 servings of pork belly, please).
3. "Mul jom ju-se-yo" (물 좀 주세요): "Water, please!". In most Korean casual spots, cold water and cups are self-service (Self / 셀프).
Side dishes (Banchan) are almost always free and refillable. Simply say "Banchan deo juseyo!" (More side dishes, please!).
