Gwyneth Paltrow

8 AM - Join Hollywood's Liquid Craze at Moon Juice
Gwyneth Paltrow drinks a smoothie featuring Moon Dust (powdered blends of adaptogenic herbs, $55-$65) every morning: "Power Dust to soothe overworked muscles, Beauty Dust for a glowy complexion and healthy hair, Brain Dust to combat mental fogginess, Dream Dust when sleep has been evasive, Sex Dust, for, you know, and Spirit Dust to get that extrasensory perception going." The juicery, which originated in Venice Beach five years ago, is now serving in Beverly Hills and also counts as fans A-listers Rachel McAdams, Kristen Wiig and Rooney Mara. With its rainbow of chilled juices (they come in literally every color), cleanses, tonics and milks, and Alchemy Bar, there's an abundance of ways to stimulate the day. (8463-3 Melrose Place)

Jim Gianopulos

12 PM - Order Fish and Chips at Neptune's Net
Continue along PCH to grab lunch at this classic Malibu outpost, which sits just east of the Ventura County line. The beloved seafood shack serves lobster and beer with a great view of the coast, making the long drive worth it for many locals wishing to give their visitors an adventurous afternoon. "Out-of-towners always want to go to the beach," says the longtime 20th Century Fox studio exec. "Neptune's Net is a great collision of biker and surfer culture. You pick out your lobster, sit down and eat it with a plastic fork with a bunch of bikers." Also on the menu: Clam chowder and shrimp baskets. (42505 Pacific Coast Highway)

Reese Witherspoon

2:30 PM - Hit Up Hungry Cat (It's 5 O'Clock in New York)
Once you drive inland, head to the Hollywood version of the original (and now-shuttered) PCH location. This seafood-centric spot was a Santa Monica neighborhood hangout for Michael Keaton, Reese Witherspoon and Kate Hudson and continues to lure fish lovers with its clams with chorizo, oysters on the half shell and sea urchin so fresh you scoop it out of the shell yourself. Get whatever ceviche is available. Plus, seasonally fresh cocktails are still the best here. (1535 Vine St.)

Jennifer Meyer

5:30 PM - Sample the Goods at Barneys Beverly Hills
The hip retailer has recently transformed its best-selling floors while launching Freds, the restaurant replacement for Barney Greengrass — making Barneys the next stop for a retail therapy-happy hour combo. Headed by chef Mark Strausman, the eatery has been spruced up by TriBeCa architect Steven Harris, also responsible for the makeover of Barneys on Madison Avenue. The 3 to 7 p.m. Sunset Menu features an infused-tea program, juices and Cote d'Azur with crudites. And breathtaking terrace views. As for the retail, Jennifer Meyer, who launched her delicate jewelry collection in 2006, says, "It didn't change my business — it made my business." A.L.C.'s Andrea Lieberman — a former stylist for Jennifer Lopez and Gwen Stefani whose wearable separates start at $185 — and jewelry designer Irene Neuwirth also found a retail partner in L.A.'s Barneys.

Kim Kardashian

8 PM - Score a Rooftop Dinner Reservation at Catch
The Catch restaurant brand, headquartered in New York's Meatpacking District, now has a just-opened L.A. address in West Hollywood. The 12,000-square-foot rooftop space — welcome to A-listers (Kim Kardashian left seclusion to attend sister Kendall Jenner's 21st birthday there), sports stars (David Beckham, anyone?) and a parade of event planners who have set industry bashes — is a splashy success. The Hollywood seafood super-scene trafficks in truffle sashimi ($24) and an in-your-face exclusivity underscored by the doorman out front, a rarity for the L.A. restaurant world. Given its overwhelming popularity, Catch's owners say they've temporarily suspended its OpenTable account, meaning you have to know somebody who knows somebody if you want to make your way in. (8715 Melrose Ave.)

Michael B. Jordan

10 PM - Flock to Hotspot Nightingale for Drinks
Tech meets nightclub at the the newest addition to Hollywood nightlife, a hotspot joining West Hollywood’s ever-growing arsenal. Michael B.
