Niz Burger Euljiro serves handmade burgers in Euljiro, Seoul. The signature Niz Burger uses a smashed patty with green vegetables on a bun toasted until crisp, adding a light charred aroma. Cooking starts after ordering, and food takes about 15 minutes to arrive. The shop has four tables for two to four people and counter seats by the window, and ventilation is poor, so the smell of burgers stays on your clothes after the meal.
