Here’s a fun thing to do over the long weekend. Check out the first ever Mushroom Festival at The Ferry Building Marketplace. Far West Fungi and Ferry Plaza Farmers’ Market join up to celebrate culinary mushrooms. There will be Mushroom Growing Tables, a Farmer Talk with John Garrone of Far West Fungi (Sat 10am), a Mushroom Cooking Demo with Chef Bryan Waites of Medicine Restaurant (Sat 10:30am), Music, Mushroom Displays and a Children’s Coloring Table. Throughout the weekend, Marketplace merchants will offer mushroom themed tastings and demonstrations. The event will benefit the Mycological Society of San Francisco.
