The Manhattan Project

Great article in the SF Chronicle:

The best Manhattans slide easily down the throat. They linger on the palate, dance on the tongue and tickle the tonsils for a good long while. Manhattans, when made by a master of the craft, can produce euphoria in discriminating souls, and they've been known to tempt angels to return to physical manifestation, just for one more sip.

Martinis, on the other hand, get you drunk quickly.
