Sunday brunch near Times Square
We also like Marseille for brunch (or dinner). Another nice option in that area is the West Bank Cafe (42nd and 9th), which serves good contemporary American cuisine in a quieter atmosphere; well-chosen selection of wines by the glass, too.
Reservations for both can be done through Opentable.
For a lunch menu (which we prefer) rather than breakfast foods, I highly recommend Maze, at the London Hotel, Gordon Ramsay's more casual restaurant. Superb cuisine, excellent service, and pleasing ambiance.
We also like Marseille, the attractive, bustling French/Mediterranean brasserie. The menu has a mix of breakfast and lunch dishes
Both restaurants accept reservations.
