Loads of famous folks live--and eat, drink, shop, and play--in New York City and Los Angeles, which makes celebrity-spotting an easy travel bonus. You just need to know where to look.
New York City
Barneys New York
660 Madison Ave.
Whether browsing the trendy togs or snacking at in-store Fred's cafe (Mark's Madison Salad, $23), Halle Berry, Katie Holmes, Chloë Sevigny, and other fashion-forward bold-facers flock to Barneys's Madison Ave. flagship store.
Fifth Ave. and 90th St.
Buy a pretzel ($2) from a cart, grab a bench near Engineer's Gate, and watch as runners descend from the reservoir loop, a favorite route of Nicole Kidman, Madonna, and other stars with carbs to burn.
The City Bakery
3 W. 18th St.
What Benjamin Bratt, Harrison Ford, and Susan Sarandon order at The City Bakery remains a mystery, but the odds are that admitted chocoholic Jimmy Fallon is after the hot chocolate served with a homemade marshmallow ($4.50).
Jeffrey New York
449 W. 14th St.
Jeffrey, a compact department store of cutting-edge styles, anchors the downtown shopping circuit of deep-pocketed fashionistas such as Hilary Duff, Sarah Michelle Gellar, and Jennifer Lopez. Even the lipsticks are spendy (Nars, from $23).
Madison Square Garden
Seventh Ave. between W. 31st St. and W. 33rd St.
Score cheap b-ball seats (from $10) and train your binoculars courtside. Tyra Banks and Rosie O'Donnell are fans of the WNBA's Liberty, while Beyoncé Knowles, Leonardo DiCaprio, and the ever-present Spike Lee follow the NBA's Knicks.
58-60 Ninth Ave.
Style setters such as Gisele Bündchen and the Williams sisters crowd this Meatpacking District café-lounge, which is open until 5 A.M. on weekends, for the perfect late-night nibble: mini-burgers ($5 for two) and fries ($3.25).
259 W. Fourth St.
Folks both famous (Drew Barrymore, Sarah Jessica Parker) and fashionable (Helena Christensen, Michael Kors) who live in the 'hood rely on this West Village café for Italian treats (biscotti assortment, $7) and coffee (cappuccino, $4.50).
The Spotted Pig
314 W. 11th St.
The concept? Pub (Brooklyn Lager, $7) with good grub (Roquefort burger and frites, $15) and a hefty side of stars: Russell Crowe, Billy Crudup, Jake and Maggie Gyllenhaal, Jay-Z, Julianne Moore, Edward Norton, and Natalie Portman, to name a few.
13-25 Astor Pl.
The East Village outpost of the omnipresent coffee chain is where Ashley Olsen sometimes fuels up before class at nearby New York University, as does her dropout twin sister, Mary-Kate. Matt Damon is also a regular. Venti sugar-free vanilla nonfat latte ($4.40).
26 Little W. 12th St.
Lounge of the nanosecond, Tenjune is tucked below STK steakhouse and packed with booths in which Penélope Cruz, P. Diddy, Janet Jackson, Nick Lachey, and Kanye West have snuggled (though not all together). Tenjune Toast vodka-and-champagne cocktail ($14).
8221 Sunset Blvd., Hollywood
A list of who hasn't graced the Chateau would be shorter. Lunch on the patio (wild salmon with sautéed veggies, $25) and keep your peeps peeled for Colin, Leo, Keanu, Jude, and Justin--and the ghosts of John Belushi, James Dean, and Jim Morrison.
The Coffee Bean & Tea Leaf
7915 Sunset Blvd., Los Angeles
Ground zero of online celebrity gossip, this java joint is the "office" of blogger Perez Hilton. Heath Ledger and Michelle Williams, Lindsay Lohan, and Parker Posey have all popped up in Hilton's workspace, and later in his column. Ice Blended Mocha ($3.60).
9071 Santa Monica Blvd., West Hollywood
The Italian dishes (spaghetti with meat sauce, $22) are old-school delicious, but it's the dim lights and private booths that keep Drew Barrymore, George Clooney, and Jerry Seinfeld coming back. Paris Hilton and Nicole Richie even ended their feud here.
8100 Melrose Ave., West Hollywood
Marc Jacobs, Anna Sui, and other designers hang on the racks, while everyone from Cameron Diaz to Arnold Schwarzenegger browses the expensive and irresistible offerings at this amalgam of chic boutiques. Cosabella lingerie from $16.
8029 W. Sunset Blvd., Hollywood
Scenesters like Lance Bass, Jared Leto, and Lindsay Lohan put this lounge on the map--and in the tabloids, thanks to Paris Hilton and Shanna Moakler's well-publicized brawl. Dress sexy, arrive early, and be prepared to wait; Hyde only fits 100. Drinks from $11.
115 S. Robertson Blvd.
Glamour gals Paris Hilton and Jennifer Lopez love the trendy clothes here. Harajuku coin purse, $12.95.
Laurel Canyon Dog Park
8260 Mulholland Dr., Studio City
You might not recognize Buckley, Obie, or Sidi, but you know their respective owners: Justin Timberlake, Annette Bening, and Orlando Bloom, all of whom have let the dogs out at this popular pooch playground.
Paradise Cove Beach Café, Malibu
28128 W. Pacific Coast Hwy., Malibu
Gain entree to the tony Malibu shoreline with breakfast at Paradise Cove Beach Café (huevos con tortillas, $8.95). Then stroll along the Pacific surf, a favorite outing for Brad and Angelina (and Maddox), as well as the often-shirtless Matthew McConaughey.
634 1/2 N. Robertson Blvd., Los Angeles
Featuring teeny togs and pimped-out cribs, Petit Trésor is the unofficial outfitter of Hollywood's baby boomlet. Britney Spears, Jennifer Lopez, and Tori Spelling shop here for their own and others' offspring. Kaloo newborn-size teddy bear booties ($24).
Saks Fifth Avenue
9600 Wilshire Blvd., Beverly Hills
Site of Winona Ryder's shoplifting bust, the Beverly Hills Saks also attracts starlets willing to pay, including Courteney Cox Arquette, Gwyneth Paltrow, and Hilary Swank. Ryder pinched Donna Karan socks ($80).
Whole Foods Market
11737 San Vicente Blvd., Brentwood
Paparazzi stalk the Brentwood Whole Foods parking lot to snap Marcia Cross, Jeremy Piven, Nick Lachey, and Reese Witherspoon loading up on groceries. Be sure to pick up this season's hottest handbag: a green store-logo tote made of recycled plastic ($1.99).
