The burger's namesake feature is that delectable garlic butter that they cook everything in at teppanyaki restaurants (at least they do here in the U.S.). McDonald's butter blend includes paprika, black pepper, ginger, garlic, and onions.
The burger also comes with a grilled, skinless chicken patty, grilled onions, and cheese on a black and white sesame bun.
It's being featured along with a spicy chicken sandwich, the McSpicy with Cheese, as part of a limited-time, spicy promotion.
