Suggest shop for banknotes in Switzerland (Geneva, Zurich, Laussane)

Hi fellow collectors,

Any suggestion on good shops to visit for banknotes during an upcoming trip to Switzerland?

I found this other thread, but it is not banknote specific. Looks like many of these are focused on coins and/or auctions

Any help will be appreciated.

Here's a list from Numista's Outings section (ICON next to FAQ under you My account). Hope that helps!

There's an excellent one in St Gallen, lovely old guy who runs it, speaks English. Got a wide selection: https://g.co/kgs/gtpU359

Thank you.

St. Gallen will be a bit far from the itinerary, but thank you!
