"We normally check out the latest on the underground scene on this site: http://supperclubfangroup.ning.com/
Beware, the quality tend to vary a lot. We can definitely recommend Fernandez & Leluu, charming and good food. If you are looking for something different and more intimate in Central London, try Cadrega, a new Italian Supper club in Marylebone, with really excellent food, freshly homemade pastas, etc. (only problem is that they only take 6 bookings per dinner...) Also, we loved Friday Dinner Secrets, run by an anglo-argentine couple. Great food in a lovely settitng. This is in Reading, but for us it was worth the trip!"
