At Busan Station, Olive Young Busan Station (2F waiting hall inside the
station) opens 8:30 am to 10 pm, so early KTX riders can stop by; the outside Busan Station Store (197 Jungang-daero) opens 11 am to 10:30 pm. Pasta Chips come in 3 flavors with 16K+ reviews. Snacks aren't liquids, so carry-on is fine; pack them on top so they don't crush. Recs: 2
