Reserve your fondue lunch or dinner in advance at Fondue Igloo on its website.
For the best deal, make sure to buy a combi ticket, which includes the round-trip journey on the cable car and the fondue.
We'd recommend lunch in the igloo if you're with young children. It's cold, even during the day, so dinner would be colder!
The Fondue Igloo is open from mid-December through early April.
