Subway has opened its 500th store in the UK and Ireland, at Bristol International Airport. The site is the brand’s first in an airport. Sue Pasco, the outlet’s owner, said: "As the world’s largest sandwich franchise, with more than 23,000 restaurants in over 80 countries, the brand is recognisable and trusted for international visitors using the airport." The chain plans to open a further 1,500 outlets over the next six years across the UK and Ireland.
