A long time ago on another board we had a long discussion about why Chicago is a pie-less island in the middle of serious pie country-- start driving through any of the states around us (especially, but not only,
Michigan) and you've got pie everywhere. Yet in the city, nuthin'.
I developed an elaborate economic theory about it, which is as good as any. Basically it's that the Greek-owned coffeeshops don't come from a southern/midwestern tradition where pie is important, so even if they offer it, it's industrial-made pie, they don't care that much about pie. And the Okies and Iowans and such who emigrated to work in industry here would have brought their love of pie, but the kinds of places they wound up opening tend to be such tiny snack shop places that they don't have the space to create and bake something like that from scratch; the same capital that would get you, in a farm town, a great big restaurant with plenty of room to bake in instead gets you a tiny place with a grill and a half dozen seats at the counter in the city. So you stick to what you can fry or buy, basically.
This links to one really good pie I found commercially (and to the discussion I was talking about). But I have to say, I still don't have an answer to your question of where to sit and have a cuppa joe and a piece pie.
