Bradley's restaurant in Fitzwilliam Street, Huddersfield has closed after 21 years in business.
The restaurant, which has featured in the Good Food Guide for 20 consecutive years, failed to re-open on Friday after its New Year break.
Owner Andrew Bradley told the Huddersfield Daily Examiner that he had fallen out of love with the restaurant trade and would be concentrating on his outdoor catering business instead.
"It's the end of an era, not just for me but for my staff and customers," said Bradley, who opened the restaurant in 1993.
"There is nothing suspicious about this. We had a very good year financially last year but the restaurant industry is a tough game and I have decided the time is right to call it a day."
The restaurant's lease expired in January 2014 and has since been operating without one.
Bradley, who has the catering contract for Huddersfield YMCA at Salendine Nook and has also provided catering for a range of outdoor events, said: ""It's been a long time and it gets harder and harder. I am not getting any younger though I am certainly not retiring.
"I want a new challenge and will take a few months off and come back and continue with my catering business. Not many people work in the same job for 21 years."
The two chefs he employed at the restaurant have since found new jobs.
