James Corden has admitted he was “rude” and “unfriendly” during an incident that ended with him being banned from a New York restaurant.

The actor and comedian was short-lived no access to Balthazar in Manhattan last week after its owner, Keith McNally, said in a social media post that he had been “very unpleasant” to his staff on two occasions.

Addressing the incident on the latest episode of his talk show, The Late Late Show, Corden said it was never his intention to upset the restaurant workers.

The 44-year-old added that immediately afterwards he was “walking around thinking what I didn’t do anything wrong“.

“I didn’t yell or scream, I didn’t stand up, I didn’t call anybody names or use derogatory words,” he said on the CBS show.

“But the truth is I made a rude, rude comment. And it was wrong. It was an unnecessary comment, it was unfriendly to the server.’

The Gavin and Stacey star explained that after seeing Mr McNally’s post, he contacted him “immediately” and they had a “good chat”.

“He appreciated that call. I was happy that we were able to clear the air. And I felt like we dealt with it privately … but by this point the story had gotten out and more people were upset,” he said.

After Mr McNally posted the story online, it sparked outrage on social media, with Corden showing his audience some scathing tweets written about him.

“I get it. I totally get it. I get that everybody’s upset and I accept everybody’s opinion,” he said.

He added that he hopes to return to the restaurant when he returns to New York to “apologise in person.”

What did Mr. McNally say happened?

In an Instagram post, the owner of the popular restaurant described Corden as “the most abusive customer to my Balthazar servers since the restaurant opened 25 years ago.”

He claimed he was “very nasty” to a member of staff after finding a hair in his food.

Calling the revelation “diabolical”, he added that the manager at the time was “profusely apologetic”.

Calling him a “little cretin”, he claimed the celebrity demanded a round of free drinks “right this second” and also wanted the restaurant to “take care” of all the drinks that were served to his table.

In a second incident, Mr McNally claimed Corden complained that “his wife’s omelette had a bit of white mixed in with the yolk”.

His message continued: “The kitchen reworked the dish but unfortunately sent it with home fries instead of salad.

“Then James Corden started yelling like crazy at the server, ‘You can’t do your job!’ You can’t do your job! Maybe I should go to the kitchen and make myself an omelet!”

However, hours after he announced he was “86”, Mr McNally posted another post to say the ban had been lifted after Corden apologized.
