The Thomas Bradley scale is a measure of the tastiness of the ‘parmo’ based on the experiences of his eponymous founder - a prodigious and widely renowned consumer of the dish.
Bradley is widely known in the North East for his dedication to a parmo only diet - a commitment he maintained throughout his later years.
Mythology has it that Bradley often lavished himself with bottled Coca Cola which he would pour ravishingly over his face to remove the remnants of the Parmesan cheese.
“Hey Byson, you got a Parmo from Bueno last night, how are they?”
“They’re definitely an 8 on the Thomas Bradley scale La - they would have got his fingers going ten to the dozen.”
