We're coming to NY this weekend and will be taking the train home on Sunday, from 3-8 p.m. Would like to get some good take-out to eat for dinner on the train. Great sandwiches would be fine, or anything else that doesn't need heating or refrigeration and will keep for several hours. Anyplace on the west side would be fine. We're leaving from Penn Station but may go up to the Museum of Natural History on Sunday, so either of those neighborhoods or anyplace in between would work. Please help!
