I have three London pub-related questions.
1. What are the two or three best pubs to visit for classic English beers -- ales, barley wines, etc.?
2. What are the two or three best pubs to visit for artisanal, not necessarily traditional English beers? (Like lots of stuff on tap, "craft" beers, etc.)
3. Where might I find the most authentic IRISH pub experience in London (I'm thinking a perfect Guinness), if that's even possible.
