Along with Rivella and Luxembergerli, the third must-try food items on my list was rösti in a traditional Swiss meal. Rösti is a Swiss dish made of coarsely grated potato, shaped into a round patty and pan-fried. It is basically hash brown, Swiss style. The best place to try this dish along with traditional Swiss sausages supposedly would be Zeughauskeller.
Three things made my must-eat list prior to the trip: Rivella, Luxemburgerli, and a meal of Swiss cuisine with some sausage and rösti. A third of the mission was accomplished on the Lake Zurich boat trip where I tried Rivella for the first time. Luckily the rest of my mission also worked out quite well.
