When it comes time to eat, grill, attack, devour that meat, these are the best places to purchase it.
Paulina Market is the cream of the crop of meat markets (ask any chef in town); just don't go on a Sunday...it's closed. I learned the hard way.
Yet another reason to head ALL the way up North: Jerry's Quality Meats. Your Jewish grandma won't be disappointed.
Gepperth's: the meat market where all Lincoln Park foodies buy their meat.
The very friendly guy behind the counter sold me some of the best burger and brat meats I've had in chicago.
The north side is good for a lot of things (the Cubs?), but especially Holzkopf Meat Market.
Cue the party hats and noise makers - Publican expanded to have its own meat/sandwich/awesomeness shop right next door to the original!
The Butcher & Larder is good on so many levels; on their own and also for what they supply to local restaurants. Chicagoans can't get enough of their meat.
