Maybe I'm weird (and I've been accused of that before), but I can't think of a single beverage that tastes better to me through a straw.

All cold drinks taste best (to me) direct from a glass (and, I mean one made of glass). Hot coffee, tea and cocoa taste best drunk directly from a ceramic mug. I can't think of any other hot drinks I've had recently, but I suspect I'd pick the ceramic mug for them also.
