Divertimenti in London run lunchtime cookery classes. If you're as bad as me at cooking then it's certainly an adventure! Each session covers somethign different - I did a one hour session which covered really quick dinner party meals. You get to taste everything you cook so it's not as if you miss your actual lunch and you head home with a copy of the recipes.
It's cool because you don't have to tie yourself into three months of classes and it gives you a bit of inspiration.
