A New York style Jewish deli on El Cajon Boulevard in San Diego whose menu it says is 100% vegan, from bagels and Reubens to knishes and matzo ball soup. It offers gluten free bagels and publishes an allergen chart for gluten, soy and sesame. Its bakery case can carry nut items, so ask, the kitchen has the final word.
