The ka'abah of burgers, the Shake Shack, opened yesterday, two days ahead of schedule. Already the lines were long—not Kate Moss long but long nonetheless. Today (with Richard Blakeley) we trekked up there to see if the burgers are as good as last year (they are) and to see if the place is as filthy as last year (it's not). Some new tricks are afoot, most notably the Shack Wands which vibrate lasciviously when your order's up. Also: potato buns for hot dogs, wind power and organic trans-fat free fries and the challenges of drinking root beer floats as a Jew.
