Plan the first visit around steak, then come back for sushi and seafood

If the table wants the clearest version of the concept, focus on the prime dry-aged steaks or the authentic Japanese Wagyu/Kobe beef. Those dishes are the strongest signals of the steakhouse side of the menu.

A return visit can lean more toward seafood and sushi. Miso glazed Chilean sea bass, sushi and sashimi platters, specialty sushi rolls are all part of the confirmed signature-dish set, so the restaurant does not have to be approached only as a steak dinner.
