I had a few ideas as to what “vomitorium” meant but I’m sure none of them were this:
A vomitorium (plural: vomitoria, slang: vom) is a passage situated below or behind a tier of seats in an amphitheatre, through which crowds can exit at the end of a performance.
From a friend who just got back from Japan. Cookies+ (wheat), Kinako (soybean flour) Bar, Jasmine Tea, Matcha Green Tea, White Chocolate.
Edit (August 2010): I added writeups of the kinako and jasmine tea flavors.
