Apparently, this is old news, because they were released in Japan in mid-2007, but I just discovered these Nintendo DS alcohol-related titles.

How well these titles compare to bartending reference books remains to be seen, but there would be a certain amount of cool-factor in looking up drink recipes on a DS. Here's a page from a Japanese website that has several screen shots (no pun intended) from Bartender DS. If any of these "games" come to the U.S.A., I'll buy them on principle alone.
