Deokhu Seonsaeng Gwanghwamun D-Tower is a Chinese restaurant on the fourth floor of Gwanghwamun D-Tower in Seoul, serving Beijing duck and regional Chinese dishes. The Beijing duck is eaten by wrapping the crisp skin and moist meat in thin pancakes, and the Sichuan-style stir-fried clams are typically ordered with noodles added. Same-day reservations are taken by phone rather than CatchTable, and arriving without a reservation at 6:20 p.m. can mean being seated at the bar because the tables are full. Prices are high relative to the menu, and some dishes such as hongyuchosu come in small portions.
