Be careful where you dine if you're being unfaithful to your partner - that's the lesson learnt the hard way for a man who was snapped with his mistress by a food critic.

During a question and answer session, an anonymous woman revealed to a Washington Post food critic Tom Sietsema she found out her husband was cheating on her.

"Well Tom, your latest review is accompanied by a picture of my husband dining with a woman who isn't me!"

She told the critic once she showed her husband the photo he confessed to the ongoing affair.

"Please, please tell me this is a crank post. I'd hate to learn otherwise."

He the screenshot of the question on his Twitter account.

"So, this popped up on my live online food chat today. Cheaters, take heed!"
