Nostress Burger is a hamburger shop on the Haebangchon hill near Noksapyeong Station in Seoul that sells cheeseburgers. It builds on one cheeseburger, with a choice of one, two, or three beef patties, and each patty comes with cheese, ketchup, mustard, and pickles. The kitchen is open and the shop has about six tables, so a wait forms at weekday lunch and on Sunday late afternoon. The ketchup and pickles are generous, which makes the burger salty and rich.
