When I visited my sister in Lucerne, Switzerland she introduced me to this really delicious cheese pie. She said it's one of the must try food when in Lucerne and I should not miss it. Conveniently located just before you go inside Lucerne’s Old Town, it will definitely grab your attention not just because there is a big yellow sign but its smells phenomenal while its being cooked on a rotating oven like device just on the street.
