The Austin burger and taco scenes are each down one member after some recent shutters. Mighty Bird closed its location on Anderson Lane. It was the only remaining location for the local chain that opened in 2013. A cryptic Facebook post by One Taco, a taco trailer which also has a brick-and-mortar location, hints that it will take the place of Mighty Bird. Rooftop burger joint Silo on Seventh, which opened in 2014, also closed recently and deactivated its Facebook page.
