The plentiful offerings at this café attract enough people to make seating at the small tables a squeeze, but the plate-glass windows, vintage posters, classical music, and an enormous selection of pies, cakes, tarts, and cheesecakes are worth it. Somehow a camera crew fit in here to film Tom Hanks and Meg Ryan parleying in You've Got Mail. Anything from sardines to sandwiches and brunch items are served daily. Reservations essential. Subway: 1, 9 to 86th St.
