There’s a funny feeling you get in Mexico City when you come back to a neighborhood you both remember and forget. Food here gets that way, too. “You know that one quesadilla joint, that one time, with the good salsa.”

There’s more to downtown D.F. than tourist attractions, however. It is the cultural, political and economic heart of the city and the country. Any item imaginable can be bought downtown. There’s the lighting district as well as one for appliances, clothing, electronics, printing and a long list of others. For generations, people have been going there to buy by the piece or wholesale to supply small businesses all over the country.

Colonia Santa Maria La Ribera, one of our favorite dining neighborhoods in Mexico City, is home to the historic kiosco morisco. Built in 1884, the Moorish open-air pavilion represented Mexico at the St. Louis World’s Fair in 1902 and has been in its current location since 1910. Just a few steps west of it sits a nondescript hole in the wall, which figures as prominently as the kiosk in our mental map of the neighborhood. Owner David García Maldonado offers just a few items on the menu, two of which are outstanding: pozole, a broth made from pork and maíz cacahuazintle, or hominy, and goat birria, a typical soup from the state of Jalisco.
