Everyone else has pretty much said what needs to be said, so I'll just add one bit. In the states, beer is traditionally served cold. The colder the better. Many of us feel that warm beer tastes awful. Many of us are wrong. American lagers do taste awful if they're warm. In England, however (maybe elsewhere also, I've never been to Europe), beers are more commonly served cool or room temperature, so those beers tend to taste better warm. They're often packaged for export to the US and sold as "pub ale". Boddington's, in my experience, is the one most commonly available on draught at bars, but most decent bars will have something either in bottle or on tap. Maybe take a look at some brands of pub ale to look out for. Newcastle brown ale is also English, fairly common, and doesn't taste too bad warm although it's better cold. A good pub ale actually tastes better cool or at room temperature, to me anyhow.
