In a rare sighting of the Queen out in a private capacity, the 91-year-old monarch was spotted heading into top notch London restaurant The Ivy for a friend’s birthday party.

She was without husband Prince Philip (95), who last month announced he was retiring from his public duties.

Despite the cold, rainy weather, the royal looked regal in a silver embellished dress and black paisley printed shawl as she arrived in a limo in London’s West Street.

According to MailOnline, the restaurant was closed to the public for the invitation-only event which also saw Prince and Princess Michael of Kent attending.

The Ivy also makes a departure from the Queen’s favourite – and supposedly only restaurant of choice – Bellamy’s in Mayfair. She was last spotted there last year with her daughter Princess Anne and Princess Alexandra and it’s believed to be the only restaurant she has ever dined in.
