Ido Chai

About

Casual Chinese eatery in Magok connecting underground passages, known for fiery seafood jjamppong, stir-fried ganjjajang, and free self-serve rice.

Tucked into the subterranean corridor linking Magok and Magoknaru stations within the One Grove complex, Idochai pares the sprawling Chinese restaurant template down to a focused handful of dishes. The sleek interior carries subtle Hong Kong stylistic notes, set up comfortably for office workers on lunch breaks and solo diners stationed at the bar counter. Seafood dominates the noodle lineup, spearheaded by the fresh clam jjamppong. Eschewing pork entirely, the kitchen builds its broth on a pure seafood foundation, loading the bowl with scallops, large clams, baby octopus, and a sizable whole prawn among flash-seared vegetables. It is fiercely spicy—striking the throat with an unapologetic kick that rivals fiery packet ramyun—yet finishes remarkably clean. For warmer weather, the seasonal cold jjamppong (naengjjamppong) trades shells for a whole abalone and strips of jellyfish, tossed with springy, chilled noodles in a vinegar-sharp, tingling broth. If spice is not on the agenda, the menu accommodates with mild baek-jjamppong, while the gan-jjajang delivers a deeply savory alternative. Freshly tossed upon ordering, the thick chunjang sauce carries robust sweetness, garnished with crisp garlic flakes over bouncy noodles. Crisp, handmade gun-mandu (fried dumplings) round out the table, packed tightly with seasoned pork and chives that spill rich juices when snipped with scissors. Idochai operates with contemporary efficiency: diners browse, order, and pay via individual tabletop kiosks stocked with soy sauce, vinegar, chili powder, and broad, lightweight soup spoons. Alongside cold pickled radish and zha cai at the self-service station sits a communal rice cooker offering complimentary steamed rice. Dipping a bowl of warm grains into the leftover gan-jjajang sauce or the stinging seafood broth ensures not a drop goes to waste.
