If the series is Bravo's Top Chef , then the tour will be about cooking and food. And that's something most people can relate to.
"It's a great concept, going around New York, tasting, talking to people, experiencing places," said Anthony Tieu, of San Francisco, one of eight people who showed up on a recent day for the tour, which is called In the Steps of a Top Chef.
Participants on Tieu's tour were a mix of locals and out-of-towners, devotees of the series and folks who'd never seen it. But they had one thing in common: "All of us like food a lot," said another person in the group, Susan Yun, a New York caterer.
The Top Chef series is a reality competition in which chefs are given cooking assignments, then judged by foodie superstars like Jacques Pepin and Lidia Bastianich.
Each season is filmed in a different city; the sixth season, set in Las Vegas, just concluded. The walking tour includes venues from the fifth season, which took place in New York.
But the tour is much more than a series of tastings. It also includes tips, quizzes, history, and even a chance to meet a chef who was a contestant.
"I wanted to design the tour to be fun and interactive, like the show, and to really give people, in a fun and entertaining way, an idea of what it's like to be a real chef," said Joyce Weinberg, who offers the Top Chef tour and other food-theme tours through her company, City Food Tours.
In addition, Weinberg's guides are all trained chefs. Yun and Tieu's tour was led by Nicole Harnett, who offered commentary on everything from techniques for cooking chicken to the differences between cheeses from sheep, goats and cows.
As with many other tours inspired by TV shows, like Sex and the City or Gossip Girls , there is no formal relationship between the tour and the show. A spokeswoman for Bravo had no comment on the tour.
One of the most popular stops on the tour is 24 Prince, a bistro co-owned by chef Nikki Cascone, a contestant on the show.
The tour group sits at the bar, takes a trivia quiz, and enjoys snacks like flatbreads topped with cheese and vegetables. Cascone drops by whenever she's available to chat and share her experiences from the show, which included being vetted by lawyers and mental-health professionals.
"They don't want us throwing knives at each other," she said.
While the show is being filmed, she added, contestants are isolated from the outside world.
"Someone's telling you when to eat, when to go to the bathroom, you don't know where you're going or how much time you have," she said. When the season was over, she kept having "nightmares about the clock."
The tour itinerary may vary, but other stops include a Chinese bakery, a grand Beaux Arts building called Capitale where the show's semifinal competitions were held, and a Little Italy store called Di Palo's Fine Foods, where contestants shopped. Participants sampled three cheeses at Di Palo's and especially liked cacio di bosco, a Tuscan pecorino with black truffles.
The tour starts outside the French Culinary Institute, where an event from the show was filmed and where Pepin is the dean. The takeaway tip here: The school restaurant, L'Ecole, offers elaborate meals at a discount, prepared by students and instructors.
There's also a visit to Broadway Panhandler, a cooking-supply store, for a workshop on knives where you learn the difference between honing steels, which are used to realign knives, and diamond steels, which are used to sharpen them.
Last stop on the tour: 'wichcraft, a restaurant owned by Tom Colicchio, the head judge of Top Chef . Sandwich samples are offered along with a tasting quiz to identify a powdery red spice, various seeds and dried beans.
The top scorer wins a carrot peeler, and everyone goes home with a list of tips (heat your pan before adding oil, but not with butter), along with a packet of fancy gray Celtic sea salt.
The final tip from the tour guide: "Don't waste the sea salt in water you're boiling for pasta."
