That said, there's no issue in Helsinki. Big shops and malls are open until 8-10, some smaller shops might close around 18 but they have to go home to feed their families.
The 24/7 lifestyle might be convenient, but I've never thought I might need it.
So yes it would be infinitely boring for someone like me to live in a city like that, it's a deal-breaker.
Other stores close 9pm. Bars are open till 2am, night clubs 4 or 5am. Some places stay open but they can’t serve alcohol in the morning hours. Getting food after 12am is trickier but there are restaurants that are open until 4am.
And it’s dark. And people on average go to work early and clock out early. And definitely not new york or berlin nightlife wise.
Talking about helsinki here pre covid regulations.
Edit: reading other comment, it’s true most speciality stores which only have one set of employees close 6-8pm. Larger chains are open till 9pm
They said it was some sort of strict cultural thing. Everyone wakes up early and you got to get used to that early schedule. And I've been a life long night-hawk.
Not talking just about bars either. I have multiple 24/7 convince stores and gas stations near by. And Uber Eats shows quite a few options at 1am on week nights.
