Yolk

A sandwich shop with a proper point of view, Yolk deals in bold flavour combinations and refuses to serve a dull lunch — an approach that's earned a 4.2 rating from 341 reviews. Doors open at a bleary-eyed 7am on weekdays for early risers around Bermondsey and Waterloo, and with dog-friendly outdoor seating alongside takeaway, delivery and dine-in, it works as well for a quick grab-and-go as it does for a lingering bite.
