It is unlikely that you will find Masonic Lodges listed in Yellow Pages, but try under Masonic Halls in your local phone book. As most halls are only open at the times of meetings very few of them have someone to answer the phone.
Please take the timie to visit www.grandlodge-england.org (sorry, I can't the blue clicky thing) and you will find a greaat deal of information. Certainly they will put you in touch with your local Lodge.
You can also book a guided tour round Grand Lodge, Great Queen Street, London, if you are so inclined.
