MK Restaurant Terminal 21 serves Thai suki and shabu-shabu on the fourth floor of Terminal 21 in Bangkok. The menu centers on duck and clear-broth suki, with dim sum and seafood sets also available. Orders are placed on a touchpad without staff contact, and most tables were still full at 2 p.m. near the end of lunch. On weekends, public holidays, and at peak hours, there is a wait and food takes a long time to arrive.
