Rikimaru Shinsaibashi is a yakiniku restaurant in Shinsaibashi, Osaka, where you eat wagyu and beef without limit. Courses that include wagyu run for 90 or 120 minutes, and you grill the meat yourself over a charcoal brazier. After booking, you may still wait outside until a table is ready. Even if you order tongue 20 minutes before the order cutoff, it may not arrive within your time.
