I've had the Imperial Torte a couple of years ago in Vienna.
It was quite memorable because the room service folks put "Happy Birthday, Debbie" on it.

I know they can ship it to the US... but is it really a good idea in this kind of weather?(it's been quite warm here lately) If anyone has any experience in this, please let me know how the Torte turned out upon delivery in the US.

By the way, I also noticed there's another famous torte called Sacher-Torte. Any comparison between the two?

Thanks for any info!
