Are you me? We also cancelled the Barbican sub last year after attending yet another performance where the audience was aggravating (late arrivals, constant beer/toilet runs, chatting), the toilets backed up yet again, broken lights still not fixed from the last time we were there (exit lights, really obvious in a darkened theatre), etc. I used to love love love going to performances there (and we like obscure electronic acts) but that night broke us. We haven't been back since.
The city vibe has changed completely - it was on the turn in 2019 but post Covid forget it. Go in to central for the office once in a while and its total tourist chaos. We live in a suburb area which is fine, but we've found we don't really use the city anymore either. Partly its due to my developing some mobility problems, but also what/where are we going to go? You can only see so many Donatello exhibits, the street food markets/shopping areas are corporatised, and everything is set up for tourist Instagram shots. Im just... bored? There used to be a feeling of authenticity and never knowing who you may meet at the office, the pub, some weekend hobby event but now the city just seems a shell of what made it great 10, 15, 20 years ago. Im sure to someone in their mid 20s just arriving its great for them and worth the price they pay, but needs change in life.
We are likely leaving next year for many reasons, but it helped to realise that we could live somewhere else and just rent an Air BnB and 'work' remotely in London for 4-6 weeks at a stretch if we really really wanted to do the city thing for a bit. Far better value!
