an Ann Arbor institution that has to be the most overrated deli in the world. Not that it's bad. It just doesn't live up to its reputation, unless what you're looking for is a Midwestern translation of an upscale New York deli (which, if you're actually used to New York delis--unfortunately a dying breed--you almost certainly are not), with New York prices and beyond. Actually, some of its products, like bagels, are affirmatively bad, which would be forgiveable given the location if Zingerman's didn't have it's own bakery.
If you're in Ann Arbor and find yourself with a hankering for New York-style food, I recommend NYPD, a pizzeria with two locations. It doesn't compare with the best of Brooklyn, but it's way better than anything I've found in the entire D.C. metro area, so far.
