Downtowner Burger
The Jamsil branch of this popular Seoul chain sits on a corner of the Songridan-gil food and cafe street. The burgers are made with tasty, lean patties, and the buns are super fresh. They also have great fries and a number of soft drinks to choose from, as well as craft beers on tap. It's rare to get a premium burger in Seoul that doesn't break the bank, and Downtowner definitely delivers in this regard. Be prepared to wait, as there's almost always a line.
