Wagyu from $72 on the menu we read · up to $115
Why it's listed
A waterfront steak and seafood house on the Royal River marina in Yarmouth, with indoor, deck, catwalk and lawn seating over the boats. Its Premium Steaks and Chops list names a source for nearly every cut, and the Wagyu runs to a 6oz A5 Japanese Tajima strip at $115 alongside an 8oz Australian Margaret River Wagyu Manhattan strip at $72. Wagyu shows up in easier form through the rest of the day too, from a grilled Wagyu teres major entree at $52 to a double Wagyu burger on the lunch and brunch lists. The kitchen serves lunch, dinner and brunch seven days a week.
Authenticity flags
- The Wagyu teres major, the Wagyu bistro filet at brunch and the Wagyu burger name no country of origin and no grade, so only the two strip steaks state where their beef comes from. Ask before ordering if the sourcing matters to you.
