As it is on the Dollar Menu, it is offered for $1.
The burger reminds me a smaller version of the recent Cheddar Bacon Onion, but somehow the one I ordered contained more onions than the "premium" Cheddar Bacon Onion that I tried. The onions were grilled to the point of charring and delivered a strong, slightly sweet flavor uninhibited by any sauces or other powerful flavors. I worry that the amount of onions given will vary wildly from location to location marring what should be a consistent experience.
McDonald's hamburger patty might be the smallest in the business, but that works to its advantage here as the flavor of the cheese and the onions are on full tasty display. It's certainly not a burger patty to strive for, but size notwithstanding, it is pretty standard as far as fast food chains go.
The cheese is a very mild cheddar and provides mostly a nice creaminess that doesn't overpower the beef of the burger patty.
The bun had a nice squishiness and wasn't too dense or light. McDonald's regular hamburger bun is actually very nice.
The overall result is a pretty good burger that actually lives up to the name. As long as you like a mild cheddar and grilled onions, there's simple enjoyment to be found in the new Grilled Onion Cheddar Burger.
