Number Ten Wine Bar in Lavenham has been saved after a change of use application posed a threat of closure.
The property 10, Lady Street is currently occupied by family-run eatery Number Ten, which has been there since March 2013.
Simon Turner and Holly Bellingham have owned the 15th Century, Grade I listed property since November 2001.
In January, the landlords submitted a change of use application to Babergh District Council proposing a change to residential, retail and function hall use, which would force Number Ten to relocate.
The business owners instructed a solicitor to object to the planning application and stated they would be considering legal action if it is approved.
However, after 75 objections were lodged, Babergh District Council rejected the application.
Acting on behalf of the building's tenants, Druces LLP believes the application to be invalid, saying incorrect use classes were used and the planning statement provided was "insufficent".
They also highlighted that 20 members of staff and four chefs would lose their jobs and free use of an upstairs room for book clubs, language classes and research groups would cease.
