Buttons and portabellas are for amateurs, right? Okay, but if you believe you're ahead of the game with shitakes and chanterelles, you'll change your mind after tonight's eye-opening Kitchen Table Talks: Magnificent Mushrooms at Viracocha (998 Valencia Street at 21st). Millenium's executive chef Eric Tucker will demo and serve a shroom-y snack while advising on choosing and cooking the most delicious fungi. Also included is a poisonous mushroom-eating challenge and educational panel on medicinal and scientific benefits by cultivation experts. Factor in complimentary food and wine and the whole experience is more than worth a suggested donation of $10, especially if you don't die from the poisonous mushrooms. [The Feast]
