London knowledge:
Welcome:
- Cloakrooms at the Royal Festival Hall, Queen Elizabeth rooms, Purcell, National etc - pretty much all of the South Bank centre.
- Most restaurants at the Brunswick centre in Bloomsbury.
- Various pubs and restaurants in the West End - the key is to act like you expect them to accommodate you. They generally will, and if they don't, you leave.
- Fitness First in Angel have kept my bike behind the reception desk for me. As has the Caledonian Road Tennis centre.
- I have also checked my Brompton at the Royal Albert Hall and at even a few night clubs before.
- The Oxford Tube will take it down below (though I recommend you D-lock it in a folded position to deter opportunists when the bus makes stops - and beware, if the compartment is empty, it will be thrown around when the bus brakes)
- South West Trains, obviously.
- TfL - provided it's folded. I've taken my Brompton on many a bus and overground train. Never tried the tube tho.
Not welcome:
The Mitre pub near Hatton Garden. There just isn't room, to be fair, but they can be really shirty about it.
On reflection, I'm surprised to find that I've never tried my luck at a cinema. Anyone have experience?
