Yet another London thread, my sincerest apologies 
I’m unexpectedly on my own in London this weekend and have had a tough week with work and some bad news.
Looking for recommendations of nice things to do, or treats that are fine for a solo traveller and will help cheer me up!
I’ve done most of the usual sightseeing-type things previously as I’m here a fair amount (workweek commute). I’d just like to let go of the stress of this week and it’s tricky without my usual home comforts.
TIA
