Although it's not as big as some of the city's other markets, this lively mercado just a couple of blocks from Frida Kahlo's house is one of the most popular with visitors, in large part because of the famous food stalls at its center doling out plates of delicious ceviche, octopus, shrimp, chicken tinga, picadillo, and other fillings for about MP40 to MP50 per portion. But you'll also find aisles of the usual fresh juices, produce, spices, candies, and other goodies typical of Mexican markets as well as a number of souvenir and homeware vendors (mostly near the northwest entrance) and many other food vendors. Arguably even better than the tostadas are the quesadillas sold from a tiny little stand at the west entrance, directly across from pretty Jardín Allende, a small landscaped park with benches and pathways; on weekends, artists sell their wares in the park and a DJ spins traditional Latin music, which locals of all ages dance to---it's great fun to watch. For a sweet treat, stop by Chocolate Mexicano Dulce Olivia, which serves sipping chocolates and carries a vast array of artisan chocolate bars produced by small, often family-run makers from throughout the country.
