"While all of the carts in the Portland Mercado are worth sampling, Tierra Del Sol is a Mexican standout for its substantial tlayuda, a thin grilled corn tortilla that’s big as a plate and plenty for two, served open-faced and topped with chicharron, black beans, Oaxacan cheese, cabbage, tomatoes, avocado, and more. It might seem easy to skip the tetelas stuffed with creamy beans and rich Oaxacan moles, though it’s not recommended." - Krista Garcia, Eater Staff
"Located at the Portland Mercado, Tierra del Sol focuses on Oaxacan classics. Arguably the most popular order is the Oaxacan tlayuda, a serving-plate-sized grilled corn tortilla, mounted with a host of toppings, such as chicharron, avocado, Oaxacan cheese, tomatoes, cilantro, and more. A single meaty tlayuda is enough food for two. Tierra Del Sol is open for walk-up orders and online ordering." - Nick Woo, Janey Wong
"Tierra del Sol’s two eastside locations offer three different moles daily (with masa dumplings, enchiladas, or chicken). They also serve tlayudas and tetelas." - Nathan Williams
"The great thing about Portland Mercado’s cluster of Latin American food carts is that diners can mix and match cuisines from all over Central and South America. But no visit is complete without Tierra del Sol’s tacos, all served on organic blue corn tortillas. Owner Amalia Sierra serves three of her deeply complex moles — a dark and robust coloradito, a vegetal pipian, and a bright and lively amarillo — in tacos, an ideal solution for those wanting to try all three. The cart also offers fillings like carnitas and chorizo." - Nathan Williams, Ron Scott
"Chef Amalia Sierra’s Oaxacan moles and crunchy tlayudas are highly praised, but her tacos are equally as enjoyable. Like many other Portland restaurants, Tierra del Sol uses Portland-based Three Sisters Nixtamal, but the unmistakable flavor of blue corn stands out in these handmade tortillas. There are three meatless fillings — mushroom, cactus, and veggie stew — which come sprinkled with pico de gallo, avocado, onions, and cilantro. Tierra del Sol has two locations: a spot at Rocket Empire Machine food hall in Montavilla and a cart at Portland Mercado on Foster." - Waz Wu
