As you know, Switzerland is one of the most expensive countries in the world. For a little comparison, the price of a small Big Mac meal is CHF 11.70. Not forgetting that MacDonalds in Switzerland is supplied primarily by local producers with products of Swiss quality and origin.
In Switzerland, it is easy to find large fast food chain stores, but there are also low-cost canteens where you can eat. These are usually found in department stores here is the list of the most well-known.
Pay attention to opening times, during the week Swiss shops generally close around 7pm except Saturdays when they close at 5pm. Opening times vary from one region to another.
The last few years have seen the development of train station shopping centres where you will easily find supermarkets. Their opening times are equally long, and above all, most are open on Sundays.
