I'm completely fascinated by this establishment on SE 41st and Raymond called the Busy Corner Grocery. It's basically a cafe, with an old grocery cold case from the fifties, table of produce and a couple of bookshelves with some dry goods. The cold case has mostly beer and wine, and a few dairy products. There are maybe a total of six or seven produce items at any given time, two of which are always lemons and tomatoes.
They serve fabulous coffee, and menu is limited to a cheese plate, a salami plate, three or four sandwiches, and whatever pasta dish or salad the proprietor feels like cooking/has the ingredients for that day. Their daughter is a fixture in the place and everyone knows her. Their dog hangs out in the doorway. They're never in a rush, and if you go there, go there to hang out because that's what the place is there for. It's not a "full service" restaurant. It's a place you can go to drink coffee or libations and a family will cook something up for you if you like. That's pretty much it. It's a very "slow food" sort of place.
This is all set up in a sort of classic looking general store style building. I love it there, and it's definitely the way I would want to do business if I were inclined to get into that sort of business again.
