The Double Oklahoma Wagyu is an onion-style smash burger made with Wagyu beef, layered patties, griddled onions, Hawaiian buns, and the restaurant’s house sauce. The Oklahoma technique presses onions into the beef as it cooks, creating browned edges and a sweet-savory onion crust. Its compact format delivers crisp beef, soft bread, and sauce in quick succession, with the double patty adding a richer, heavier bite. The restaurant’s menu and description specifically identify this burger as part of its Oklahoma-style Wagyu lineup.
