Visiting local open or indoor markets and supermarkets are one of the best ways of getting to know…read morelocal culture when visiting somewhere new, so I try to visit at least a couple examples of both whenever I'm traveling to a different country.
Mercado de Coyoacán popped up as a convenient option since it's within a 10 minute walking distance from both Museo Frida Kahlo and Museo Casa Kahlo. Open since 1921 (though originally in a different location), on an early Sunday afternoon this appeared to be a popular place to visit, with plenty of people eating lunch at the many food stands, picking up groceries as well as a number of tourists exploring the aisles.
The market is divided into sections, another Yelper compared it to Ben Thanh market in Ho Chi Minh City, Vietnam (aka Saigon), and I'd agree this reminded me of a smaller version of that, and the setup is very similar! And by smaller by my estimate there's still more than 150 vendors here, so relatively speaking tons to explore (if that gives you an idea of how large BT market is)!
Different sections of the market sell different items, there are areas for apparel, accessories, vegetables and fruit, butchers and seafood, spices/condiments/sauces, dried goods and coffee, food stalls, handicrafts and souvenirs interspersed in between. Each stall has a number tho you may need to do some wandering around to locate a specific one if you're searching for it.
Vibrant sights, smells and sounds greet you at every corner, since it was around lunchtime the delicious scents of food wafting around made me hungry!
I ate at one of the more popular stalls and food was decent though perhaps not stellar imho. However I may not have ordered the right items and it was also one of many choices so I'm sure there are other tasty items to try.
The aisles are very narrow, enough for one person to pass thru in some cases, so take that into account. Bathrooms are available though not clear on conditions. Cash is preferred, or required at some stands, and a number of vendors also take credit cards with chips.
