Monday 20 at 6:30pm - Burns Night at the Pickwick - Sorry the pub is full, and also on 27 January. Next year I must remember to try to book 2 months in advance. Reserve by 16 January for the Burns Supper of the Swiss British Society (CHF 50) which is on Saturday 1 February.
Instead, on Monday 20, attend the Light Festival of Murten. Meet at 6 pm at the Berntor gate of the town (30 minutes by train from Berne) and at 6:30 pm for an Apero on a boat in the lake. For details see www.icberne.ch/item/1245069
