How much is a coffee in Swiss francs?

Could you please elaborate on the cost of a coffee in Swiss francs? Is there a standard price across all coffee shops in Switzerland, or does it vary depending on the location, quality of the coffee, and additional services offered? Is there a significant difference in price between a simple espresso and a more elaborate coffee drink? Also, how do the prices compare to other popular beverages or food items in the country? Thank you for your insights.
