Why it's listed
Inside Beacon Hill's XV Beacon hotel, Mooo.... is a fine-dining steakhouse where Wagyu spans both Japan and the US. The menu names a Japanese A5 sirloin from Kagoshima Prefecture plus American Wagyu cuts sourced from Snake River Farms (Idaho) and Rosewood Farm (Texas), each listed with farm, weight, and price; Japanese Wagyu also appears in dumplings and the signature burger. With multiple whole-muscle Wagyu steaks and transparent sourcing, it clears WagyuSpot's focus bar. A5 is applied only to the Japanese cut. Open daily and not listed in the Boston Michelin guide.
