Fans of eight-month-old Mateo's Taqueria (2471 Mission Street) — which is probably many of you, given that after eight months, and amongst stiff competition in the Mission, enjoys a four-and-a-half-star average rating on Yelp, which is basically the best anyone can hope for, and the same rating that Saison and Benu have — will be glad to know that owner Matt Ishak is already expanding. As Hoodline tells us, he'll be taking over one of the four vacant retail spaces in the base of Uber HQ at 1455 Market Street — two of which were formerly a McDonald's and a Happy Donut, if you want to talk about Mid-Market gentrification.

The key to Mateo's popularity is obviously it's bright and clean atmosphere, commitment to good ingredients, good tasting Mexican food, and keeping prices mostly under $10 — the most expensive menu item is a fish burrito for $11.

As Ishak says via the restaurant's Facebook page, "We are committed to bringing you the best ingredients free of GMO’s, natural and organic as much as possible. We cook for you, like you are family."

There are hand-made organic flour tortillas from Sonoma, organic corn tortillas from La Palma, and plenty of care given to the meats and fish too. Mission Local gave the place a rave last fall, not long after they opened, calling out the carne asada and the fish taco especially.

Not to be confused with Mateo's Cocina Latina in Healdsburg (no relation), Mateo Ishak grew up in San Francisco and worked as a kid in his grandmother's café in Noe Valley, bussing tables, and eventually moving into the kitchen.

The second, Mid-Market spot, given its audience, will likely feature breakfast starting at 7 or 8 a.m., and will stay open to 7 or 8 p.m. on weekdays, to start. Ishak is hoping for a mid-summer opening.
