So I come from Omaha, and ground beef at the grocery store is gourmet in New York, so I have to say that if you need to season a steak it's not a good cut of steak. Salt and pepper or other maneuvers are up to taste, but beef is cursed to be fucking delicious. Especially corn fed beef. I would think a wagyu tomahawk is a sirloin, right? Looks like it. My uncle always said he loved t-bones because he gets the sirloin and the ribeye. Tomahawks look like a bit of a show piece, but bone adds flavor to everything.
