‘Game of Thrones’ SXSW Event in Austin Includes Free Shack Burgers - Eater Austin
"Relatedly, Shake Shack is also offering a festival-specific burger at its two Austin locations (one on South Lamar, the other in the Domain). The ATX Wagyu Burger is made with a Texas wagyu-blended patty where the meat is sourced from Mahan Wagyu Ranch in Silverston Texas, cheddar cheese, griddled shallots, and grainy mustard-mayonnaise. It’s available from Friday, March 8 through Sunday, March 17." - Nadia Chaudhury
