The Real Cheese Burger is a handmade cheeseburger shop near the Gyeongui Line walking path in Hongdae, Seoul. Its signature Double Cheese Burger comes with grilled onions, two patties, and two slices of cheese, with no vegetables by default; pickles, lettuce, and tomato can be added. Around 1 p.m. on a weekday, there was no wait and the food came out quickly. Menu explanations at ordering are limited.
