I believe the chicken dumpling is the regular soup that they offer every day and then they also have a second option that changes. I think in all the years I've been stopping there for soup there was only one time that they were out of the chicken and dumpling and didn't have it. It's my favorite soup and one I know I can stop and get whenever I get a taste for it.
Oh, the sandwich menu there is awesome with lots of "grinder" options.
Here's a shot of dad on one of our visits to Mancino's with a bowl of the chicken dumpling soup. :)
