Coffee shops, bars/pubs, cinemas, theaters, opera houses, bigger and nicer libraries, real, physical bookshops (at least for people like me, who visit them regularly like how other people are going to church), and I’m sure I must be missing some other stuff.

As an anecdote, I went through a dark time about 10 years ago and living in a big city and being able to see strangers each and every day on public transport helped me tremendously, it meant not having to live with my dark thoughts. I could have not had the same experience had I lived in suburbia or in the countryside.
