Firefighters scrambled to Tracks and Records in Montego Bay, St James, after members of the eatery's meal preparation team discovered the fire at around 1.45am local time on Saturday.
The top floor of the venue was engulfed when crews arrived, but they managed to contain the fire - which remains under investigation - and reported no injuries.
Acting Superintendent Oneil Kerr, the Jamaica Fire Brigade's lead investigator for St James, said: "Upon arrival, the team observed fire coming from the roof of Tracks and Records.
"They immediately got into operation, and within a few minutes, the situation was brought under control.
"The fire was confined to the upper floors, which hold the dining area, bar, restrooms, and an office space.
"But as it relates to getting the property owners to do their evaluation of the items they had stored, that will determine the full cost.
"Based on observation, the extent appears to be significant."
The restaurant, which is located on the Hip Strip - one of Jamaica's tourist hotspots - has not yet opened back up to the public.
Officials spent Saturday morning sifting through debris and taking statements from members of staff.
The cause of the fire has not been determined, but there has been unconfirmed speculation that it was caused by power returning to the building.
Tracks and Records - which the retired eight-time Olympic gold medalist sprinter opened in 2018 - had been relying on a generator for power because its electric mains had not been fixed following the devastating Hurricane Melissa.
The restaurant - which serves up Caribbean cuisine in a sports-themed setting - had been feeding communities devastated by the catastrophic tropical cyclone, which became the third-most intense Atlantic hurricane on record.
In the wake of the category five hurricane, Bolt - who retired from athletics in 2017 - also distributed care packages at his former school, William Knibb Memorial High School in Martha Brae, Trelawny Parish, which was damaged by Melissa.
In a video shared to X, he said: "I have seen all the videos … and people always say it is so much more different when you see it in action.
"On the way up … at the riverside, you see a lot of people washing, it's hard to put into words how I feel about what I am seeing, but Jamaica, I am here to help in any way possible."
Bolt captioned the clip with: "J A M A I C A, You all gave me the chance to represent you on the world stage — to wear our colours with pride, show the world the strength, resilience, and the heart of our people.
"Everything I've achieved started right here at home. Now, as so many of our children, brothers and sisters face the hardships caused by Hurricane Melissa, please know - We are right here with YOU. We are STANDING together, REBUILDING together, and reminding the world that JAMAICANS never leave each other behind (sic)."
