Did you know that this date clashes with another (non EF) social event, in Fribourg?
I think there's an indoor climbing facility at Givisiez, but Paddy Reilly's nr. the station, could be a good meeting point.

[or is this a cryptic event arrangement - driving me up the wall?]

needs date.... please add.

depends on who is coming, but perhaps in the morning to give some time for drinks later on.
