"We called the pest control man straight away and got rid of the rat. We have always had a good record with the health inspector."
The restaurant was able to show documents indicating a pest control business had visited the eatery in 1/10 Minto Rd, opposite the railway station, less than three weeks prior.
Campbelltown Council city development director Jim Baldwin confirmed an environmental health officer attended the premises on Thursday.
"The offending pest had been caught and contained," he said.
"The officer's inspection revealed nothing to validate a closure of the premises and records were presented to prove pest treatment in the last few weeks. This venue has a good compliance record and strong history of appropriate compliance with the Food Act 2003.
"A thorough inspection of the premises was conducted and minor corrective actions were suggested that will be followed up by council to ensure that they are addressed appropriately."
Mr Baldwin said there is no known rat problem in Minto.
