Pret a Manger is an international sandwich shop chain based in the United Kingdom, popularly referred to as Pret. Emphasis is on the use of natural ingredients and sandwiches that are made on the day of purchase. Sandwiches are packaged in paperboard rather than sealed plastic. You won’t find ‘sell-by’ dates on the freshly prepared sandwiches and salads and the milk and coffee is 100% organic. Pret offers unsold food to charities at the end of each day.
