Starbucks St Pancras is open 24 hours.Can anyone suggest somewhere selling coffee at or very near Euston station that might be open at 5.30am on a Saturday morning?
Have checked the hours of all the places I can think of but no luck.
So far as I can see Burger King isn't open that earlyEarliest I could find on google maps was the Caffe Nero which opens at 6am, other options are either the Burger King (do they even serve coffee?) and the Avanti lounge
