My favorites are two kinds of 'special' beers, Belgian, Triple Karmeliet and Kwak. The last one comes with a very interesting glas construction too. It was used like this for coachmen, because it wouldn't spill as easily when driving. I've been in a place where you had to give them one of your shoes, so you wouldn't steal the glass and you would get your shoe back when you returned the glass. Those two I can highly recommend if you on the other side of the pond get the chance at one point.
Otherwise, I agree with Basil that white beers (witbier) is nice. A summer beer that tastes a little fresher than normal pilsener
