This is a HUGE shocker to anyone who is used to walking in to Arby's hoping for a choice other than a sandwich meat. Arby's announced it's adding the "Wagyu Steakhouse Burger," which costs $5.99, as a limited-time offering. In their 60-year history they have never offered a burger. They say it will be quite impressive as they have spent more than two years developing it. The burger is a blend of Wagyu beef and ground beef and will be "highest-quality burger the market has seen yet," the company said. Who is IN??
