Rock Villa is a kimchi sandwich cafe in the Tsuruhashi Station shopping street in Osaka. The signature kimchi sandwich is cut into bite-sized pieces and contains cucumber, ham, egg salad, and mayonnaise, served with siphon coffee. Morning service runs from 8 a.m. to 11 a.m., and the sandwiches are available for takeout. Smoking is permitted, so cigarette smell can cling to your clothes.
