At Kendall College of Chicago this weekend, that will be more a glory than a gag. Connoisseurs of fashion have been rolling the names of clever Belgian designers off the tongue for more than a decade--Dries van Noten, Ann Demeulemeester--but the reputation, and snob appeal, of Belgian beer and cuisine remains more exotic. From a kingdom half the size of Lake Michigan, more than 350 different concerns produce 800 types of beer, over 100 of which will be represented this weekend at Chicago's first Belgian Beer Celebration.
