Bonanza Coffee Gunja Flagship is a coffee shop across from the main gate of Eorini Daegongwon in Seoul. It serves espresso and filter coffee, along with baked goods such as financiers and carrot cake. Orders are placed at a kiosk, and the second floor has about 30 tables and 50 seats. The windows look onto Eorini Daegongwon, but on weekend afternoons the café is crowded and good seats are difficult to find.
