Downtowner Busan Lotte Gwangbok sells handmade burgers and sits on the first basement floor of Lotte Department Store Gwangbok in Nampo-dong, connected to the subway. Its signature avocado burger combines avocado with bacon and cheese. The shop runs without a break and has ample seating, so it suits visits at off hours. Drinks and handmade pickles are self-refilled.
