Billion Box Gangdong Myeongil is a small handmade burger shop near the entrance of Myeongil Market. Its main menu is the tender chicken slider, and you can choose spicy chicken tender inside the burger or as a side. The Tender Slider Classic contains two chicken tenders and uses a soft, corn-bread-like bun that is easy to bite into. The burgers are as small as french fries, so you need to eat several at once.
