Oishikatsu is a Japanese restaurant in Dongseongno, Daegu, serving thick tonkatsu. It fries sirloin katsu and tenderloin katsu until crisp, and the charcoal-grilled sirloin katsu carries a light smoky note. The kitchen uses low-temperature frying, so orders take about 20 minutes after they are placed. Counter seats look into an open kitchen where the cooking takes place, and food arrives later than at other restaurants.
