I've been getting takeout from Real Kitchen for a couple of months. It's in a little strip mall at the corner of Montrose and Clark. All pre-prepared foods to go and explicit instructions for how to reheat it at home. The food offerings change regularly, but everything I've ever had there has been terrific: Beef bourguignon, homemade pasta with meatballs, brased veal, grilled vegetables...the list goes on.
Price are reasonable. Last night, I got a delicious hunk of braised pork over polenta with some yellow sqush and peas. This would have easily been a $25 entree, but for the bother of taking out a pot to heat it, I only paid $9. For the quality, this place is by far the best deal in the neighborhood.
They also have sandwiches. I've only gotten a sandwich once, which was tasty if a little small, but also not too expensive - around $6.50. They made the sandwich to order, so there was a little wait, as opposed to the cooked meals which are ready to be picked up.
