NOT for vegetarians
First, I have long thought it is important for people to know and understand what they put in their mouths. The recent spate of TV chef focus on this subject can only be good. If you are going to eat something, you really should respect it. Meat is not an inanimate thing wrapped in clingfilm, it was once a living, breathing animal.
Second, it's always good to know where to get a good pork sandwich - Spitalfields in this instance.
