Tricks of the Restaurant Trade S02E03 - Episode 3

This episode reveals what's in some of the takeaway lunches sold by big brand names and especially whether those salads and soups are quite as good for you as you think. Could a fish salad have more calories than a fry up? And can a chocolate frozen yoghurt really be fat free? Plus: why you shouldn't eat at your desk.
