You’re in GBK, front of the line. Nervous but looking the server dead in the eye. You lean over the counter and whisper “I’ll have Jamie’s Burger”. Maybe you wink, who knows. What arrives is the off-menu special named after Mr Hyde National Burger Day creator Jamie Klingler, available until August 28: a 6oz patty, grilled in French’s mustard and topped with Red Leicester cheese, Sriracha mayo, and pickled onions.
