Wavy Burgers' signature burger features double Wagyu smash patties with confit onions, white American cheese, and chipotle aioli on a brioche bun. The smash technique creates maximum crust and browning while the Wagyu provides richness and marbling that standard beef cannot deliver. The confit onions add sweetness and depth, while the chipotle aioli brings a subtle heat and complexity. The burger can be made vegetarian with portobello mushrooms for those seeking an alternative.
