I like witbiers and have always found Hoegaarden to be a classic example. It's a shame that it's another example of a decent beer getting bought out by the faceless mega-corporation – InBev in this case. Read about the history of Hoegaarden Brewery at Wikipedia.
Still, even with corporate types meddling it's a fine beer, with the citrus and spice flavours that you'd hope for. It's a shame it doesn't go a bit further with it though, to stand out from the crowd.
