Kid-friendly tonkatsu restaurant in Dongjak, Seoul: lunch at Kosi Isu
Kosi Isu Branch is a tonkatsu and udon restaurant on Sadang-ro near Isu Station in Dongjak, Seoul. Over a lunchtime visit with the kids, cheese tonkatsu and bukkake udon (cold sauce-topped noodles) were ordered together; the lunch peak meant a 20–30 minute wait, but sofa seating made the meal comfortable, and the stretchy cheese and chilled udon pleased both children and adults. Kosi Isu Branch is an easy Isu Station pick for eating out with kids, with no menu debates needed.
