5. Morgan Library and Museum, 225 Madison Ave

The plush Morgan Dining Room is inside the restored 19th-century brownstone which was formerly the Morgan family’s home. The vintage vibe continues with a menu inspired by early 20th-century New York cuisine. Brunch includes a mimosa, brioche French toast, cookies and coffee for $25.50. And who wouldn’t want a Gilded Manhattan cocktail, made with 23-carat gold dust, whilst reading The Age of Innocence?
