Arby’s fast-food chain boasts ‘We’ve Got The Meat!” And now they have the “hamburger.” Arby’s is well-known for its roast beef, but for a limited time, they are adding hamburgers to its menu.

For the first time in almost 60 years, Arby’s is introducing the “Wagyu Steakhouse Burger.”  And it’s not just any regular hamburger. Arby’s says this new burger is a blend of Wagyu beef, and ground beef and they say it is the “highest-quality burger” in the market.

In case you’re wondering, “Wagyu” means “Japanese cow.” It’s a special breed of cow known for having a rich flavor, is buttery and tender. The Wagyu Steakhouse Burger is served with American cheese, shredded lettuce, tomato, pickles, red onion and a “special burger sauce” all on a toasted brioche bun. Arby’s claims its 50% bigger than McDonald’s Quarter Pounder.

The “Wagyu Steakhouse Burger” will cost you $5.99 beginning Monday, May 30 through July 31.
