Both wearing furry jackets and mini dresses to show off their legs, the ladies dined at the eatery in the heart of London's Mayfair district.
At one point, Lindsay looked strangely out of it while talking to a female friend during the dinner. And later, when leaving the restaurant, the actress looked at the camera with an vacant expression and her long red hair disheveled.

As RadarOnline.com previously reported, Lindsay continued to display a haggard look on Monday, New Year's Eve, as she was photographed entering the Dorchester hotel in London.
