Back to Basics 2Go, Fitzrovia, W1
Mostly a takeaway outlet for the adjoining fish restaurant, offering usual sandwich shop staples plus some other interesting stuff. However, it also has some tables for eating in, despite the name... Both closed in 2012, and the main site became Bonnie Gull Seafood Shack. This site turned into a vegetarian cafe called Kin. (Photo of breakfast.)
Address: 21a Foley Street.
