Cast your mind back to the Seventies and step inside our corner cafe. With its Formica tables and bench seating, the “greasy spoon” was a den of fry-ups washed down by sugary drinks and milky tea. Coffee was only served one way and chips came with every meal. Fast forward to the present day to a world of mochas, lattes and milk done a dozen different ways. Is the modern version of the cafe still 'chips with everything' or has it become more caffeine and protein-powered? This is the scene you have to puzzle.
