I'm not much of a beer drinker, I preffer Scotch. However I have some opinions on what I do like:
Theakston XB
Abbott Ale
Old Speckled Hen
Widmer Heffeweiss
Leffe Dark
Hobgoblin (Shepheard Neame)
Thicker and less carbonated is better

The exception to that is Budvar. A cold Budvar on a hot day is perfect.
