Time Out says
Only a few months old, Downtowner in Hannam-dong has already made quite a splash. Five burgers are listed on the menu, but there are really only three (cheese, bacon cheese and avocado) as two of them are double versions of the original. But what this place lacks in variety, it makes up for in price and a tasty selection of sides. Prices start at 6,800 won for a 120g patty cheeseburger, going up to 11,800 won for a double cheeseburger with double bacon. Downtowner also offers variations of fries, ranging from original to guacamole. The chicken strips, though, are perhaps the most interesting side on the menu. Purists will appreciate the buffalo chicken, but for something different, try the General Tso. Unfortunately, Downtowner doesn't serve shakes, but they do make up for it with an extensive selection of craft beers.
