Dongchabap is a Japanese restaurant on the third floor in Hongdae that serves sake don and tonkatsu. The sake don comes with thick raw salmon and rice dressed with sauce, along with miyeok julgi muchim, onion muchim, and gochujangajji. On a Sunday at 1 p.m., two parties were waiting ahead and the wait was 10 to 20 minutes. The space is small, so customers can wait on the rooftop.
