Les Frères Marchand
Across from the Palais Ducal, you can sink your teeth into authentic regional dishes such as quiche Lorraine, fried grated-potato râpés, or Andouillette sausage with pungent Gros Lorrain cheese. Tables inside are tight, creating a bustling atmosphere, and the quality of the service seems to vary with the weather, but the hearty food is irreproachable.
