They don't list it but if you ask for gf bread for a sandwich they have it. This is standard Westchester deli but probably the best in Rye. They also stock for purchase gf bread, muffins and other frozen food. Also have gf Tates cookies and other goodies around. They also have gf chicken cutlets which are pretty good. They do not use a dedicated fryer though fyi
They make a great bacon egg and cheese on a gluten free wrap.
