I'm in love with white chocolate. I particularly like "Green & Black's" white chocolate. They use vanilla bourbon, which makes the chocolate taste like vanilla ice cream. I also like Lindt, both for White and 85% Cacao (the 2 types I most frequently buy). IMO, the Swiss make some really good chocolate (actually, all products that they export are pretty much awesome
). I'm not a chocolate connoisseur, though, and neither of those brands are exactly super expensive gift brands (they cost about $3-4 a regular sized bar).
EDIT: Some haters will tell you white chocolate isn't "real" chocolate, but I don't care, it still tastes awesome
