I love Bewdog, their Punk IPA is really easy to drink. They make a lot of different styles, I love their Porter style beers. I had one of their 'Libertine Black Ales' last week, stunning beer that, was hoppy/ IPA style combined with a Porter finish, very nice indeed.
Belhaven is OK, its an English style IPA, not a massive fan, its similar to Greene King.
Belgium is awesome for beers, I love Trappist beers, especially brown tripel Trappist styles!
