The Private Room at The Ivy Chelsea Garden is hosting sit-down dinners and stand-up receptions this Christmas season. Its marble flooring and bold furnishings add star quality to either sort of event. For sit-down affairs, guests can line up around a single long table or gather at three separate eight seaters. Menus will be specially created by the exec chef. If there’s business – or just a festive game of Pictionary – to be done, an easel and two plasmas come as standard.
