Buongisikdang sits on a sloped one-way alley in the furniture district of Nonhyeon-dong in Seoul. It is a Japanese-style restaurant serving cheese brown tonkatsu, kimakare, and ramen. The cheese brown tonkatsu is topped with Mexican cheese, and the kimakare uses a thick, slightly spicy sauce with minced meat, garlic flakes, and raw onion. An open kitchen sits in the middle with bar seating and two- and four-person tables, and habanero powder is available.
