Mexico City can be overwhelming, especially for first-time visitors, due to its sheer size, teeming population, and–when it comes to food, in particular–enormous variety of options.
One excellent way to get a sense of the city's scope and sabor (flavor) is by taking a food tour. Two companies, Eat México and Mexican Food Tours, offer walking tours that include Polanco in one or more of their itineraries. Eat Mexico also runs market, street food, and late-night tacos and mezcal tours in other parts of the city, including the hip neighborhoods of Condesa and Roma, and the Centro Histórico.
Both companies' tours include tastings and some include transportation.
