Rosti (pronounced Rohshti) is a famous, hearty Swiss dish similar to American hashbrowns, but often served with meat and/or cheese and vegetables as a meal, skillet style.
Right in the Zurich Hauptbahnhof train station is this great, casual, little diner-style Rosti bar. It's fairly cheap eats for Switzerland- and a nice change from just grabbing a quick pre-made panini sandwich while traveling or changing trains.
We had rosti with sausage and cheese I think and I don't think it was more than about US$10 per person. The rosti was freshly made, hot, filling, and delicious.
