Trouble is if you use something in French, Italian or Spanish it may suggest that you specialise in food of that origin. Good point, dxb. How about Latin? I vaguely misremember someone posting a while ago about the variety (and impropriety, and over-satiety) of Roman gatherings -- maybe there is some Latin word that fits (and can serve as a witty in-joke for customers who are hip to the ancient jive). Lends itself nicely to classy logos with columns and laurel wreathes and such, too.
EDIT Found it! The word I was thinking of is perfect (and it nicely crosses-threads to a "below the fold" forum). The
convivium was the more gentle, classy counterpart to the more rowdy Roman parties we usually think of (according to the below post from Whit). How about Convivium (or to pluralize, Convivia?)? Sounds like "convivial" but has that semi-exclusive feel you only get with Latin.
