My local Arby's has them on the menu for $4.49 each.
King's Hawaiian bread is known for it's dense and squishy soft texture and just the right touch of sweetness. I've eaten a lot of sweet breads/dinner rolls and King's has always been my favorite. It tastes great buttered and grilled on a Spam and egg sandwich, but I wasn't sure how it would go with Arby's signature roast beef...
It turns out it goes quite well. The extra portion of beef supplies an ideal amount of savory beef flavor and a delicate tender texture that fits well with the bread's slight sweetness. It's just the right amount of meat to balance out against the pickles and dijon sauce.
The pickles are deli-style pickles with a good crunch and a bit of a sour bite that's interesting without ever being overpowering.
