Zaidy's is the most overrated "deli" I've ever tried. The food is Jewish deli style in name only and the bagles are round white bread. Try The Bagel Deli on Hampden for something much, much, better.
Best Deli for Breakfast - 2008
Zaidy's gets rave reviews from the locals, but you'd be better off at Denny's or (shudder) The Village Inn. Nasty doesn't begin to describe the food and both locations I've visited have been dirty.
I am from Chicago, and I also happen to be Jewish. Not that either makes me an expert on what a fantastic deli entails, but let me tell you that Zaidy\'s is NOT it. The matzoh soup is either bland or salty, no in-between. The reuben is gross. The bagels were just pieces of round bread. Go to The Bagel on Hampden, regardless of what meal you want to eat...
