With Bonnie and Rock stunned by the tarp dividing the dining room, Chef explains that they will each be running their own half of the restaurant. Yet Chef allows them to spend some time with their families. Rock's two kids enter to his surprise. Bonnie's parents tell her how everyone is so proud. The families say goodbye. Chef encourages the two finalists to start creating their restaurants -- from décor to menu.

Back in the dorm, Rock and Bonnie celebrate together with champagne. He admits that he didn't think she'd last. Bonnie lets him know that she will beat him.

The next morning, they scan the dining room and plot what to do. Then they each meet with the Hell's Kitchen architect and designer. Bonnie wants hardwood floors and no booths. She wants less uniformity and mismatched china. Rock likes the booths and the uniformity and the classical elements. She wants color accents. Rock loves black and white. Construction begins.

Then they meet with Jean Phillipe to discuss the servers' uniforms. Bonnie likes the waiters all in black. She thinks the female staff should wear tighter pants to look sexy. Rock isn't sure, and suggests jeans. Jean Phillipe shudders, and pushes Rock against this notion.

They discuss menus with the sous chefs. Bonnie has a huge list of ideas reflecting her favorite foods and MaryAnn gets to work with her. "I feel like a kid in a candy store," Bonnie says. "I want to do it all!" MaryAnn likes everything Bonnie has put together. Yet Rock is having problems preparing his menu with Scott. His ideas aren't as clear-cut as Bonnie's and he can't narrow anything down.

Chef surprises Bonnie and Rock by letting them know that he's taking them to Las Vegas. On board the private jet, Chef brings up Rock's "hissy fit" when he lost one of the challenges against the girls. "You, my dear, have surprised me the most," Chef says to Bonnie. He remembers that she couldn't even fry an egg the first time she worked in Hell's Kitchen. Chef questions why Rock put Brad up on the chopping block instead of Josh, and Rock says that Brad was his biggest competition. "Everything I do is strategy," Rock explains.

Driving through Vegas, the pair is excited to see that the Green Valley Ranch has a huge marquee that reads, CONGRATULATIONS HELL'S KITCHEN FINALISTS. They arrive in a huge suite, where a video of them is playing on the plasma screen TV.

That night, Chef takes them for a quiet little drink. But knowing the twists and turns of the competition, Rock and Bonnie find themselves in the center of a huge surprise party. Chef introduces them to the crowd. Among the throng is Las Vegas's best chefs. Bonnie and Rock have thirty minutes to create a dish that represents their signature style. As the two get to work in the kitchen, the party-goers watch them on huge screens.

Rock is making his surf and turf -- fried chicken and crab cakes. "I took a chance with a combination that most people aren't accustomed to," he says.

Bonnie is preparing her shrimp and lobster pasta, which she feels represents herself the best. "It's not the most sophisticated dish, but it is the most full of flavor," she says.

After thirty minutes, Chef has them present to famous chefs. The first to judge is the executive chef at Ceasar's Palace. He chooses Bonnie's seafood fettuccini because her shrimp was perfectly cooked. Next up is a chef from the MGM, and Chef Ramsay chides Bonnie for trying to charm the man. Yet this guy picks Rock's dish as his choice. The following chef sides with Bonnie.

Instead of a chef, the next judge is Robin Leach, the former host of "Lifestyles of the Rich and Famous." He goes with Bonnie's dish as well. After Mr. Leach is Hell's Kitchen Season 1 winner, Michael. Rock tries to schmooze him for sympathy. It must have worked, because Michael picks Rock's chicken. Bonnie leads 3-2.

Season 2 winner Heather comes after Michael. "They're both fabulous," Heather says after taking a bite. "But I gotta go with Rock." It's now 3-3, and the tie breaker will be decided by two judges -- the Green Valley Ranch's general manager and executive chef. The general manager sparks to Bonnie's pasta immediately, but the chef seems to be going for Rock's chicken. The two guys whisper to each other before announcing that they are giving their vote to Bonnie. She wins and the crowd cheers. Yet Chef pulls them away from the party for some "quiet time."

Overlooking the city from The Palms hotel rooftop bar, Chef pours Rock and Bonnie a glass of champagne and congratulates them. "Next time one of you visits Vegas it will be to run your very own restaurant," Chef says of the view. Bonnie notes that it's just within reach. Chef presents them both with a present. It's a trip to New York to come and eat at the chef's table at his new restaurant, Gordon Ramsay at The London hotel.

Everyone returns to Los Angeles where the dining room is under deep construction. Rock and Bonnie share one last meal together in private. They talk about how the contest has changed them as people. Rock comments that Bonnie has done well, but that she "doesn't know how to finish." Bonnie takes this as him trying to use psychological warfare on her game.

The next morning, the pair is surprised when the last six eliminated chefs return to the dorm. They are happy to see their former competitors. Brad would like Rock to win. Bonnie is relieved to see her good friend, Jen. Suddenly, everyone stops when they realize that Julia is sobbing on the couch. She only just left Hell's Kitchen a few days ago and she regrets that she didn't win. As Julia dries her tears, Chef calls to summon the entire group to the kitchen.

As they line up for Chef, Julia starts to break down again. She says that the whole competition has been a high point for her, but right now is her lowest point. She calms down when Chef welcomes her back. As winner of the Las Vegas challenge, Bonnie gets first pick of the group to be her kitchen team members. Obviously, she goes with Jen, who promises to have Bonnie's back. Rock chooses Brad first because he feels he is the strongest.

Bonnie next goes with Melissa over Julia. Bonnie isn't sure that Julia can overcome her emotions today. Rock then picks Vinnie even though he doesn't think he will perform well in a high-stress situation. "Very, very interesting," Chef sighs. Bonnie's last choice is Julia. However, Julia confides to the camera that she is personally rooting for Rock. Although Rock thinks Julia is a better cook than Josh, he is worried that her emotions could play out in the kitchen. "Josh is not gonna cry," Rock says of his final pick.

Chef instructs Rock and Bonnie to take their teams back to the dorms and bring them up to speed on their menus. Bonnie is sure that the girls will overcome once again like they have in the past because they work well together. Rock proudly states that he will do anything to win.
