My preference is blond/wheat beers, anything called hefe-weitzen (methinks it's half wheat and half barley). Hoegarden is good too (I'm surprised nobody mentioned it), as is Sam Adams summer ale, cherry wheat and some blackberry one they had recently (winter ale, pale ale and the other standard ones aren't to my liking).
Crazy Horse is awesome (anyone know where I can find it in Brooklyn?), and I once had a Slovakian beer which was really good.
Some others that were mentioned which I like are Leffe and Yuengling.
Things I don't like in beer: dark beers, hoppy beers, frothy beers and heavy beers. Oh, and smirnoff ice, zima etc. aren't beer, so please don't mention 'em in this thread
