I am a sucker for good Matzoh Ball soup and the Bagel Factory's Matzoh Ball soup is one of the few that remains quite consistent and does not disappoint.
The service can be slow so I suggest calling in your order well in advance or going before the lunch rush. The last time we got The Bagel Factory, my husband seemed quite impressed with his Sky High Deli Sandwich- the hot pastrami so that was an additional bonus (he was not as much the fan as I am of this place).
P.S. I also recommend their grilled cheese if you are eating there!
