Every right thinking Londoner leaves London for the weekend and goes to clear his soot encrusted lungs with some fresh country air - don't we Ivanhoe? Accordingly residents parking doesn't apply during the weekend at all. So help yourself. There's loads of space south of tower bridge road.
Sue, i'm down the other end of Blackfriars Bridge Road from the Mad Hatter and you can park in the resident bays all weekend - best place is Gladstone Street as it's dead quiet and you can get a space at weekend - Mapmaker's spot on
I'm pretty positive that round me (Falmouth Rd) it's OK to park in residents' bays on evenings and weekends.
You could park where I leave my car, but i'm hoping mapmaker offers to whisk me away to his rustic seat in his luxury car this weekend (so my rusty old tub will, hopefully, be spared the challenge of locomotion).
It always used to be empty for a good reason [that being that it was a bit shabby and was staffed by generally sulky people and frequented by people who felt at home in that atmoshphere].
It's been taken over recently and now only opens from 5pm. I think they're trying to market it at the halls of residence immediately opposite. I've not been in since reopening, but that's because there are plenty of other nicer places to go and it doesn't really seem like it's anything other than a big room with beer taps.
But, as I've said, I've never been in. If you give it a try, then post something and tell me how wrong I've been.
