Back in April, McDonald's announced plans to add a premium Angus burger to its fast-food lineup. The burger, priced at $3.99, would compete with other higher-end fast-food burgers such as Carl's Jr.'s Six Dollar Burger and Burger King's XT burger, and was scheduled to roll out nationwide by August. Well, July's barely begun, but yesterday the chain's Angus Third Pounders hit menus across the country.

The burgers, which weigh at least a third of a pound, or 5.33 ounces, before they're cooked, come in a trio of styles, all on a sesame seed bun: Deluxe, with tomato, lettuce, mustard, mayonnaise, red onions, dill pickles, and American cheese; Bacon & Cheese, with ketchup, mustard, red onions, dill pickles, American cheese, and three slices of bacon; and Mushroom & Swiss, with mayonnaise, sautéed mushrooms, and swiss cheese.
