Leiths School of Food and Wine has been teaching cookery for over 30 years. It has a huge range of courses to choose from, such as evening drinks classes (whisky, wine and beer tasting), day, evening and week-long cookery classes (from knife skills to middle eastern cuisine), or for the ultimate professional qualification there is 1 year Diploma. Learn how to be the next Gordon Ramsey in no time, minus the swearing of course.
They also publish cool cookery books and you can hire out the whole of their fourth kitchen if you fancy having a corporate chopping session or alternative party of some kind.
