if you want to park in Westminster on 27th

I'd certainly advise checking - although local signage would be more
relevant. In my experience, there would be little problem in parking in
a side street in the area on a Bank Holiday evening, providing that
resident-only bays are not used (and even some of those are signed as
available to anyone on a Bank Holiday).
