Gyumaru is a western American-style restaurant on Tenjin Daimyo Street in Fukuoka that serves hamburger steak and sirloin gyukatsu set meals. The hamburger steak is made with beef and a house-made patty, and you can choose between onion, demi-glace, or teriyaki sauce. Orders are placed at a vending machine inside the restaurant, where you buy a meal ticket and then wait holding it. The space is small, with a few tables and counter seats.
