Instead of picking a few restaurants as an afterthought to your travel plans, why not make food a centerpiece of your trip? An array of walking tours that feature restaurants, markets and chefs makes that possible.

But choose these tours with care—some are organized by individuals who promise more than they deliver or who have little training.

Food tours typically last about three hours, cost $50 to $75 per person and provide numerous small tastes of interesting foods at eateries and markets, as well as cooking tips.* Among the best…

BOSTON FOOD TOURS

A tour of the city’s Little Italy neighborhood in the North End uncovers some of the city’s best pastry shops, delicatessens, greengrocers, spice and coffee vendors and more. The three-hour tour, costing $50, also delves into the history and culture of Italian food, with advice on Italian cooking and selecting Italian ingredients. Tour founder Michele Topor is a trained chef who has been working professionally with Italian food for more than 30 years.

A two-and-a-half-hour Chinatown Market Tour for $65 explores Chinese baked goods, barbecued meats, “bubble” teas with tapioca “pearl balls” and more, followed by a dim sum lunch. 617-523-6032, www.BostonFoodTours.com.

NEW YORK NOSHWALKS

While most New York City food tour operators focus exclusively on lower Manhattan, NoshWalks offers 35 different food tours covering all five boroughs and most of New York City’s wide range of ethnic cuisines. Options range from the Western Chinese, Ukrainian and Russian foods of the Brighton Beach Tour…to the Korean, Persian and South Asian food of the Slices of Midtown (Manhattan) Tour.

CHICAGO FOOD PLANET

The Near North Food Tour explores the food of the Old Town and Gold Coast neighborhoods. It typically includes seven locations, among them a Jewish deli, a Polish bakery, the city’s top-rated deep-dish Chicago-style pizzeria and Chicago’s oldest chocolate confectioner, with enough food samplings to comprise a lunch.

The Bucktown/Wicker Park Tour offers a look at the eateries of these decidedly hip neighborhoods. It typically includes the top-rated Chicago-style hot dog stand, a highly regarded pastry and dessert restaurant and a Middle-Eastern restaurant, among other eateries.

The Chinatown Tour offers tastes at some of Chicago’s best Szechuan, Cantonese and Mandarin restaurants.

TEXAS BAR-B-Q TOUR

The Dallas/Fort Worth region features some of the best barbecue in the world. On this tour, you sample ribs, brisket, sausage, sides and more at three of the area’s top-rated barbecue restaurants and chat with some of the pit masters. Because the distances involved are Texas-size, this is not a walking tour—a train ride and chartered bus are provided. The four-and-a-half-hour tour costs $75. 817-475-3089, www.TexasBarbqTour.com.

SAN FRANCISCO

San Francisco has the largest Chinatown outside Asia and the oldest in North America. Wok Wiz has led more than 20,000 tourists through this bustling, colorful neighborhood in the past 20 years. Tour founder Shirley Fong-Torres also is author of four books about Chinese food, including The Woman Who Ate Chinatown: A San Francisco Odyssey (iUniverse).

Wok Wiz’s I Can’t Believe I Ate My Way Through Chinatown Tour, costing $90, includes a traditional Chinese breakfast, tea in a highly rated Chinatown tea shop, stops at Chinese food shops and a sumptuous Chinese lunch. It adds up to quite a bit of eating. But be advised—this tour is meant for somewhat adventuresome diners who like to try foods that they may not have eaten before, such as jook, a traditional Chinese rice porridge.

The Wok Wiz Daily Tour explores both the cuisine and culture of Chinatown before concluding with an optional dim sum lunch. The three-hour Daily Tour costs $50 with lunch, $35 without (children under age 11, $35 with lunch, $25 without). 650-355-9657, www.WokWiz.com.
