Sam Chen is the owner of Miss Wonton, a new dumpling spot on the Upper East Side
You probably never expected to find bagels and dumplings in the same place, but now you can.
Wednesday morning was the grand opening of Miss Wonton, a new dumpling spot at 1409 York Avenue (corner of 75th Street). Miss Wonton occupies the same space as Kossar’s Bagels and Bialeys, which opened in March 2023. The owners of the two businesses have joined forces to form a partnership.

Sam Chen, the owner of Miss Wonton, told East Side Feed he’s been working with the owner of Kossar’s for many years. They own multiple restaurants throughout the city together, including La Salle Dumpling Room, which has three locations on the west side. The Upper East Side expansion was inspired by Kossar’s expansion into the neighborhood, and a desire to bring traditional Chinese hand-rolled dumplings to Upper East Siders.
“Gluten-free is really popular these days,” said Chen, “so we have a lot of gluten-free specialties.” In fact, more than half the menu items are gluten-free, and some additional items can be made gluten-free.
