I've been in a few time since moving over here. It's definitely worth visiting.
I'm sure there are other London threads here you've seen or will check out but one pub I always make an effort to visit is The Rake in Borough Market.

Also you've got lots of nice food in the Market right beside it - <!-- m --><a class="postlink" href="www.facebook.com/pages/The-Rake/147286531966639">www.facebook.com/pages/The-Rake/147286531966639
