Sorg's - Darien, WI
My parents live near Darien, and go to Sorg's regularly -- particularly for special occasions. They're pretty frugal, and wouldn't bother if the quality weren't worth it. When I'm back in Wisconsin for visits, I always request that they pick up some beef jerky for me there -- it's great.
I posted this message and somehow, it did not post. I live in Woodstock, IL about 25 miles away and I'll hit Sorgs 3-4x per year.
Some quick observations:
1) Call in advance to see when they are open. Their hours are odd and they close early on Saturday and are closed on Sunday. I have made trips up there just to find that they are closed.
2) Even if you buy only stuff from their freezer, take a number or they will not serve you. It is a Wisconsin thing.
3) Their meat tends to be better than Jewel-Osco or Dominick's (that's not saying much). Their butchers do know how to cut meat and do a pretty good job. They carry a lot of unusual items (i.e., chili grind ground beef, lamb cubes, ground lamb.
4) The prices are OK, pretty close to the normal prices of the majors.
Personally, I buy 80% of my meat at the Woodman's in Carpenterville,IL as the prices are much better for comparable quality. If I am heading off to Harvard, Darien, Janesville, or Whitewater, I will stop in and see what is available
