Thanks for the responses.
Online it appears a debate of staying in Wengen vs Lauterbrunnen.
For food we will most likely just schlep with us so we don’t have to go into Zurich.
Will look into what is available.
@VacationLover do you remember if there was anything available near where you stayed
I have read train pass is the way to go as well.
Will probably have more questions s as I continue this research.
