reforma
La Teca in Reforma is Deyanira Aquino's home-kitchen Istmo room with five tables, no sign and 30 years of garnachas-on-banana-leaf cooking unchanged.
Why locals love it: Five tables in a Reforma residential street; no sign, no website; you knock at the door.
Tip: Book by phone the day before (951 515 0563); lunch only, 14:00 to 16:30.

Mercado Sanchez Pascuas on Porfirio Diaz is Centro's locals-only morning market, with tejate, tamales and comedor counters from 06:00 in three small halls.
Why locals love it: Northwest corner of Centro, well off the tourist trail; locals-only morning market open from 06:00 with three small halls and three comedor counters.
Tip: Arrive 07:00 to 08:30 for the freshest tamales; the comedor counters (Yolis, Lupita) close around 15:00.
xochimilco
Ancestral in Xochimilco is the thatched-roof grove on Lopez Alavez, well away from Centro tourist flow, with the seven-moles tasting platter as the headline.
Why locals love it: In Barrio de Xochimilco, the weaving quarter most tourists never reach; thatched-roof grove.
Tip: Take a taxi (the Lopez Alavez block is a steep climb); book the moles tasting for two.

The empanadas-de-amarillo grandmas at Plaza Llano cook only Friday to Sunday afternoons, folding thin masa around mole amarillo and quesillo on the comal.
Why locals love it: Weekend-only street vendors that don't show up on Google Maps; a dozen abuelas with charcoal griddles.
Tip: Friday-Sunday from 16:00; expect to share a bench, the bench at the corner of Plaza Llano is the centre.

Cabuche on Hidalgo is the locals' Centro lunch room with a 100-peso comida corrida, pulque on tap and the deepest fermented-drink list in the centro.
Why locals love it: Mostly local lunch crowd with a comida-corrida menu rather than a tourist a la carte, and the deepest pulque-mezcal-craft-beer list in Centro Oaxaca.
Tip: Order the 100-peso comida corrida; the pulque-cerveza pours are the deep cut.

El Volador in the Plaza de la Danza Jardin Socrates is one of the tejate stands by the lake bandstand, whisked from cacao, maize and mamey to a foam.
Why locals love it: Half-hidden between bandstand benches on the Jardin Socrates lake, only tejate sellers know.
Tip: Bring your own gourd cup if you can; otherwise the disposable serves are 30 pesos.
