I guess I don’t really notice a big difference walking around grocery stores or shops in the city on game day. Everything is so limited on hours (compared to pre Covid) that the people watching or at the games don’t really change anything

Don’t quite get the question. With or without sports going on, there’s plenty of quiet places that are enjoyable in the city. Sissel exhibit at ICA right now is great and weird. Matisse exhibit at museum of art is great on weekdays in the mornings.
