When I lived in Toronto, I would regularly work out of a coffee shop that was open until midnight. It never really seemed worth the cost of having an employee there, but I was thankful for it. And when I was in Cambridge, 1369 was absolutely my go to.
I find it fascinating that in the 1990s, the US managed to re-create early twentieth-century Vienna café culture only to have it gradually decay over the first quarter of the twenty-first century such that now most coffee shops are closed by six PM.
