Biggest single sitting meal I ever did was a 50 oz rump at a place called the Highwayman in South Wales. Came with chips and all the trimmings washed down with guiness imported from Dublin by the owner.
Felt like Mr Creosote afterwards mind-luckily I didn't go for the 'waffer thin mint' afters
They used to do a special calle the condemned mans meal-from memory it was a 32oz t bone, pork chop,sausage ,bacon and all the trimmings-did a few of them too
