Masterbeef is an all-you-can-eat hot pot restaurant in Mong Kok, Hong Kong, serving Japanese A4+ black-haired wagyu. Over 120 minutes, diners eat wagyu and a seafood platter and can choose a mandarin duck pot that splits two broths. The dining area is separate from the self-serve corner, and Australian M9 wagyu meatballs and abalone are unlimited. A queue forms in the evening.
