Depends...
For getting drunk, it doesn't really matter as long as it's easy to drink and cheap. With food a dark czech lager, for a hot day a good hefeweizen. Just for taste I'd say Fuller's ESB, Jämtlands Hell, Guinness Special Export Stout, Sinebrychoff Porter or Chimay Blue. Or a ton of others. There's too much good beer in the world.
Yeah, I'm a beer nerd.
