THE BUZZ With studio budget cuts making the three-course lunch an endangered species, and post-9/11 security measures turning food deliveries into search-and-rescue missions, celebs and Tinseltown execs have taken to munching on this California fast-food chain’s gourmet low-fat salads, burgers, and fries. THE DISH Take Burger King and kick it up one big notch.

SCOOP DU JOUR Britney Spears, Freddie Prinze Jr., Kirsten Dunst, Eric McCormack, and Kevin Smith have all recently chewed the (low) fat. FOOD FETISH Despite the chain’s signature fluffy burger bun—engineered by chef Hans Röckenwagner—Marlon and Damon Wayans bring their own bread. FRESH SQUEEZED Prepare to wait on Fridays, when the lunch crowd can stuff the tiny mini-mall location.
