I finaly found Leo’s Bagels after my GPS and William Street downtown below Wall Street turning right screwed me up. It is not that hard to find, if you just follow the street and not the name of William Street where it turns.
They had plenty of pumpernickel bagels and a salmon spread that was pretty good but did not have the big chunks of Salmon one finds at Zucker’s. On return visits, I have really enjoyed the smoked whitefish on a pumpernickel bagel, wrapped in thin paper, sliced through the paper and placed in a clear plastic sandwich container. Fishy and messy. Yum.
