Your munchies stand no chance on April 20. There's already the 11th Annual Grilled Cheese Invitational getting cheesy at Los Angeles Center Studios. Now you can also mosey over to Taco Madness in Downtown LA's Grand Park. Co-sponsored by L.A. Taco - which is deep in the throes of finding the best taco in LA - the festival features tacos from some of the best taqueros in town, including Mexicali Taco & Co., Mariscos Jalisco, Leo's Taco Truck, Yuca's and MexiKosher, plus DJs, artists painting murals and a beer garden. The event takes place from noon to sunset and is free except for the tacos, which start around $1 a piece, drinks and other snacks.
