Bobby Flay may be sick of burgers -- and we all may be sick of burger stories -- but here's one more:
Flay, who opened Bobby's Burger Palace in University City on Tuesday to hour-long waits, stepped out for a late-afternoon field trip.
Destination: 1504 Sansom St., home of rival burger operation 500º, which opened March 23.
Owner Rob Wasserman spotted the chef on his way in and bought him a meal. When pressed for specifics, Wasserman said it was a 500º burger (medium), plus black-and-white shake, and fries.
