Arbys. its good mood food. and this is the sandwich that started it all. since 1964 weve been putting ear-to-ear grins on faces from coast-to-coast. our arby's roast beef classic sandwich has thinly sliced, oven roasted beef piled high on a toasted sesame seed bun. try it with our delicious arby's sauce, or for an extra kick go with the zesty horsey sauce
