I bought one for $5.69.
The steak was beefy and juicy. It came in a thicker cut than Arby's regular roast beef, which made for a meatier (and more satisfying) texture.
It was only the lone onion ring that manage to break through the tanginess. There might be only one but it was a large one and cut really thick to boot. The panko crust does a good job of keeping crispy as well.
Overall, while the quality of the ingredients of Arby's A.1. Special Reserve Steak Sandwich were spot on, the A.1. sauce was just too tangy for me. I would have liked it a lot better with a more mild savory sauce (or even no sauce at all). Or, maybe just a few drops of the A.1. Special Reserve since it is the key ingredient.
