McDonald's is to introduce a mammoth burger called 'Le 280 Grammes'(twice the size of a Big Mac) in its latest attempt to bring back French customers to its chain of fastfood restaurants.

The French Unit of McDonald's has suffered particularly from bad press around its corporate image in France and the BSE crisis in the last year, driving down sales in most of its outlets.
