Jaguemsong Siam Square One จากึมซอง สยามสแควร์ วัน

Jaguemsong is the Korean-Chinese noodle house on the fifth floor of Siam Square One, unit SS5016, with a 4.9 Google rating from more than 3,400 reviews. The house dish is jajangmyeon, wheat noodles under a thick black-bean pork sauce, which Grab's Siam guide describes as dense and intense; the same write-up points to a vegetable-heavy bibimbap and neatly rolled gimbap. The chain's Wongnai menu lists jajangmyeon at 220 baht, the spicy buljajang at the same price, jjamppong seafood noodle soup at 260, tangsuyuk sweet-and-sour pork at 300 and sharing sets at 799, so expect 220 to 450 baht a head. Open daily from 10:00 or 11:00 until about 21:00 to 21:30, depending on the source. A bowl of jajangmyeon and a plate of tangsuyuk shared between two is plenty.
