I’ve been there (it’s three blocks from where I grew up and my parents still live), and I haven’t tried a meal there – just the bagels (which are terrible). I was there last month, and the service was indeed lousy. The teens behind the counter aren’t particularly friendly or helpful. I will take your word that they have good soup -I can’t imagine eating anything prepared at this place, which doesn’t seem well taken care of to me. For good chicken matzoh ball soup in Chicago, I’d go to Manny’s or Once Upon a Bagel (in Highland Park), or perhaps to Max and Benny’s (also in the north suburbs).
