The KJ community guide, updated October 27, 2026, names Rabbi Mehlman for Insomnia Cookies at 1579 Second Avenue and limits its reference to UWS and UES. A current individual letter with dates and scope for cookies, ice cream, toppings or equipment was not obtained; check those details at the shop. The operator website returns Access Denied. This reference does not cover the whole chain, and vegan options do not establish pareve status. Reviewed October 28, 2026.
