POWERBREAKFAST

Regency Hotel, New York * How you know this is the '90s: There are egg substitutes on the menu and Town Cars idling where limousines once claimed the curb. How you know this is still the ultimate Power Breakfast nook and the home of Hollywood East: Henry Kissinger's got his own regular spot, and Disney's Jeffrey Katzenberg, famous for conducting two, three, four meetings in one bagel-and-decaf morning there when he's in town, is at the next table. You want to start your day moving and shaking, you come here and shake hands with Loews Hotels president Jonathan Tisch (nephew of CBS' CEO Larry, couldn't hurt). You greet manager Marie Hallas, who knows everyone. You drink your OJ. The finance crowd clocks in at 7 a.m. (hey, there's Felix Rohatyn); the politicos and real estate heavies weigh in at eight (look, it's Mort Zuckerman); the entertainment crowd rolls in at nine (Whoopi Goldberg likes her corner table). Hugo's, Los Angeles * It's Monday and Julia Roberts is in a corner reading the newspaper with her pal Jason Patric. But John-the-waiter says Tuesday is when breakfast gets really hot at this former meat market, so go figure. The rockers are the guys eating strawberries and drinking herbal tea. (David Bowie and Eric Clapton are good customers.) Don't expect to do major business before 8 a.m. (none of that crack-of-dawn stuff for this crowd), but if you do stagger in at six, you're likely to see Jeff Goldblum, who's a regular early staggerer.
