B ack in the late '80s/early '90s, the Chicago cafe scene was the match of nearly any city. And one particular joy was how many of them were open until 2 or 3am, sometimes more. I'm not talking about Denny's-type establishments, but small, hip cafes. But now it's 2:40am, and if I want to head out to a cafe, there's nothing that I know of. When I came back to Chicago in in the early '00s, the cafe scene was almost decimated, replaced by chain commuter coffee places. It's now beginning to fill out again, but none of them are open late. Cultural change? Rent prices too high to staff that late? Places I just don't know about? Several other major cities this is just not a problem.
