Thanks for all the lack of help.
Just finished my first 3 pieces of swiss kfc with chicken sauce in Switzerland.
Waited ages for this.
Took a chance this morning and got the train down via Aarau.
The kfc entrance is less than 80 metres from the front of the bahnhof. Next to the trams. Perfect location

Maybe we can close the thread now.
I did not get the menu. And it cost less than 12 chf for 3 breasts and sauce with no mashed potatoes. The extras look expensive.
Very efficient and well cooked. Delicious.
Do not queue. The ignorant gits here just barge in. After 30 minutes I decided to play their game.
