Yayoiken Across Fukuoka is in the basement second floor of Across Fukuoka and serves set meals, katsudon, and champon. Rice comes in bite-size, small, regular, or medium portions with self-service refills, and there are corners for pickled side dishes and chazuke broth to finish the meal. At the entrance you enter the number of people on a touch panel and take a numbered ticket, order on a tablet, and a serving robot brings the food, with payment at a self-checkout counter. Even during quiet hours, food takes 30 minutes to come out.
