"We know Lady Gaga is in town for her concert tomorrow night," said Arrowhead Grill owner Charles Schwerd. "If she visits Arrowhead Grill, everyone in the restaurant will get a free AG burger."

Lady Gaga is in town this weekend to perform at U.S. Airways Center on Saturday night. 

Arrowhead Grill is even renaming their signature AG burger after the pop singer. You guessed it, for this weekend it's officially the Lady Gaga Burger. 

"If you visit our restaurant this weekend and tell your server that you want the Lady Gaga burger, you'll get one free for each one you purchase," Schwerd said.
