It's an odd concept to say the least.
Little Chef has always been synonymous with egg & chips, heart-attacks and radioactive diarrhoea and tampering with that winning combination is going to be a big waste of time.
They'd be better off just literally deep-frying fat ducks and selling those as they'd do infinitely better than a half-arsed attempt at cobbling together a budget version of snail-porridge.
And you know for a fact that said snails are going to have been picked off the grate of the nearest storm-drain before being chucked into a big vat of cheap-imitation Ready-Brek.
Whatever next? McDonalds selling Kobe Beefburgers?
