London peeps - help please! Public toilet info needed (Tier 3 - will everything be shut?)

[girasol]

Hello
Bit of a random one, but we have to drive to London on Monday with our two kids (7 and 5) to go to the Spanish Consulate to renew our daughter's Spanish passport and then to go to a pharmacy near Victoria to pick up a private Covid test which we've booked.
We'll also need to get lunch while we're there so I'm assuming we'll be a good 2-3 hours plus our journey time (best part of an hour each way).
Am slightly panicking now at the prospect of London going into Tier 3 and what we'll do about toilet visits if eateries are all shut other than for take outs. Can anyone tell me, please, if the likes of Pret/Costa/McDs etc are likely still to allow take out customers to use their toilets or do they close access completely? I'm assuming it will be similar to the November lockdown.
Or if anyone can recommend any public toilet options which may still be open around Chelsea/Sloane Square/Kings Road (Consulate is a few streets north) or Victoria that would be much appreciated!

I would pretend it's all about the kids but honestly it's me and my walnut-sized bladder that is of most concern! Thanks in advance.

Toilets in the main train stations are all open so if you are by Victoria, you can go in there.

The toilets in Victoria train station will be open. Also unless I’m completely wrong shops can stay open in tier 3 can’t they? Peter Jones (John Lewis) at Sloane Square has plenty of loos so that should also be a reliable option.

Oh yes you're right @ShyTown, I'd not thought of that. Thanks! And thanks @Wiifitmama too. Phew!

Toilets in McDonalds remained open during the last lockdown, so I am sure they will this time.

You'll also be able to use the train station toilets.

I'm in a tier 3 area and toilets are all open. Even in lockdown they are.
I think shutting them in tbe first lockdown was a terrible idea.
People urinating and even pooing all over the place. Gross.
Plus it is important to wash hands regularly.

I'm in a tier 3 area up north loos are open and places like Costa etc are open for takeway so you could get food and eat it outside on a bench or something.

I m tier 3 in the midlands and I went to the loo in mcds on Friday so that is an option 😀
