The 29-year-old actress and A TIME TO KILL star McConaughey, 34 - who are rumoured to be dating - turned heads when they joined 15 friends at the capital's exclusive DA MARIOS restaurant.
And the generous pair treated staff to a GBP360 (GBP200) tip.
An onlooker tells British newspaper the DAILY MIRROR, "Penelope and Matthew turned up with their friends at around 11pm and the restaurant stayed open till two.
"They looked really smitten. They couldn't keep their hands off each other. Penelope certainly didn't look as if she still had feelings for Tom.
"They had lots of pizza and pasta and drinks. The bill came to GBP500 and then the couple gave a whopping GBP200 tip."
