Best known in western New York State, beef on weck ($10.95) piles thin-sliced roast beef on a hard roll, crusted with salt and caraway, called kummelweck. Horseradish is the standard condiment. Despite the wetness of the sandwich — Bonnie's doesn't stint on the juice, let alone on the beef — it's a thirst-inducing combination of flavors. Cole slaw dressed with red-pepper powder, and a plate of meaty Buffalo chicken wings (small, $8.95), will take you further down that road. Buffalo bar owners (so goes the story) first offered beef on weck as a way to sell more beer; Bonnie's will oblige you in that regard, too.
