The German star was invited to the chef's The Berkeley restaurant while preparing for his new culinary movie Burnt and admits the place made his tapas bar in Berlin look terrible.

"I opened a restaurant about five years ago," he explains. "What I learned is that we are very far away from getting a Michelin star! The level of perfection and the quality in this restaurant where I was trained - Marcus Wareing's restaurant in London - is just incredible."

But Bruhl will be taking a few things he picked up on set back to his Bar Raval in Berlin.

He tells WENN, "I learned a lot."
