This special restaurant definitely needs a reservation. Depending on the day you want to go even up to 6 months ahead. They only have 12 tables and you will be totally in the dark. Your guide/waitress is either blind herself or cannot much at all. You cannot take your watch, mobile phone etc. into the actual eating room but you are asked to leave the things in the lockers because of the displays that can light up. On Sundays there is a set menu for about CHF 70.00. On the other days there are 3 different menus, a couple of desserts and starters available. Sometimes they have a concert or reading for which there is a separate entry fee of CHF 25.00.
