The annual meat-free, family-friendly weekend gorge-fest returns to Seattle Center, with the usual assortment of nutrition lectures, veggie-cooking demonstrations, and, of course, tons and tons of free food. "This annual celebration of vegetarian and vegan superiority is hippie heaven," wrote Lindy Westâan unrepentant carnivoreâof the 2007 fest. "Five dollars gets you unlimited access to hundreds and thousands of samples. It's totally wonderful." (Seattle Center Exhibition Hall, March 29â30, 10 amâ6 pm, $5 adults, kids 12 and under free.)
