My husband and I are planning to spend the day in Manhattan tomorrow. We're going to take the PATH from Newark and just wander around downtown. We'll have our 16-month-old son with us, so we're planning a stop at the Columbus Park playground. Looking for a casual place to eat lunch...off-the-beaten path, any kind of food (chowpup likes Italian and Indian, but eats hamburgers or anything with french fries too). Outdoor seating would be good, but anyplace that's child-friendly is OK. Doesn't need to be right near Columbus Park, but within reasonable (15 minutes?) walking distance.
