Futago is an Osaka-style yakiniku restaurant in Causeway Bay, Hong Kong. It grills beef, pork, chicken and seafood over charcoal, including A5 black-haired wagyu galbi and a tongue platter. On Friday evenings the seats fill up and online booking is required, and staff grill the meat and serve tea and a yogurt drink after the meal. Waiting times for orders are long and service is not attentive, with water and napkins not brought out first.
