Welcome to one of this country's most delicious unknown sandwiches, the
Beef on Weck. This simple but brilliant creation features thinly sliced,
horseradish-covered roast beef piled high on a freshly baked kummelweck
roll. The roll's fragrant caraway seeds and coarse salt are a perfect
accent, and when you add a steaming ramekin of fresh beef jus for
dunking, you'll understand why this is the pride of Western New York."
