Stay safe out there! Sorry you ended up with a crappy weather day - it was lovely yesterday. It is meant to be a bit nicer the rest of the week. Enjoy your time in my fun city!
If the weather is nice, go hit up the Ladbroke Arms. Awesome gastropub not far from you in Notting Hill. Easy walk or just take the Central Line to Holland Park or the 94 to Turnham Green- St James.
