Tube ponderings with Barry Heck
Our resident tube fancier dishes out daily thoughts on the London Underground.
My Roundel of the Week, chosen with some hesitation, is this illuminated number on Whitechapel Road. It's part of the fixtures at 'Jack the Chipper', a new Whitechapel Road fish & chip shop that's not only appropriated the tube roundel, but also makes wordplay out of local murders. Plus, its door staff appear to be fatally malnourished. Not sure I approve, to be honest. Follow Barry on Twitter @HeckTube.
Good cause of the day
Book ahead for No Laughing Matter, a comedy night in aid of St Mungo's homelessness charity. It takes place on 15 October at O2 Shepherds Bush Empire with Stewart Lee, Doc Brown and Shappi Khorsandi on the line-up. Find out more and book tickets.
