Subway, the sandwich chain, plans to open 300 new sites in the UK in “non-traditional” locations over the next five years. The c.1,400-strong chain has already opened units in convenience stores and petrol stations, and will look to add further sites under these formats plus outlets in sports stadiums and army barracks. Tesh Patel, development agent, said: “"We feel it's time to get into other markets.” The chain is also understood to be trialling a new format at a handful of its sites in the UK, which if successful could be rolled out further across its estate in the UK & Ireland. The new look features a more relaxed, coffee lounge feel than the current format and includes refreshed decor. In March, Subway announced it had overtaken McDonald's to become the world's largest restaurant chain in terms of units. Subway had 33,749 restaurants worldwide, of which all are owned by franchisees, at the end of 2010, compared to the 32,737 operated by McDonald’s.
