Ivy Chelsea Garden

Housed in a nearly 300-year-old building, this lush restaurant remains one of the hottest places to see and be seen, in part thanks to the romantic green garden out back with trailing wisteria and climbing roses. The extensive all-day menu features classic English treats like toasted crumpets as well as such international fare as tuna Carpaccio with spiced avocado, crème fraîche and coriander shoots. Don’t skip the crowd-pleasing chocolate bombe—a sinful sphere of chocolate which, when doused with warm salted caramel sauce, melts to reveal a core of milk foam, vanilla ice cream and honeycomb. Reservations recommended.
