A new food truck specializing in dishes from across Latin America opened Sunday at 9426 Stewartown Road in Gaithersburg, marking the latest tenant to take over a commercial lot that has become something of a revolving door for Latin street food vendors. Trioresto held its grand opening celebration starting at noon, rolling out a menu that stretches from Mexican street tacos to Peruvian carne a lo pobre.
According to The MoCo Show, Trioresto describes itself as a Latin food truck specializing in freshly prepared dishes, with a stated goal, per the business, of bringing together traditional recipes and flavors from across Latin America in a casual, accessible setting. The truck occupies the same Stewartown Road spot that previously housed Elias Taqueria, another Latin food truck and stand that held its own grand opening back in August 2024 serving birria tacos, steak, and gorditas, according to The MoCo Show's earlier coverage of that opening.
A Menu That Crosses Borders
Trioresto's menu reads like a tour of Latin American street food. Alongside Mexican street tacos and quesabirria, the truck serves Salvadoran pupusas, Honduran baleadas, Nicaraguan tortillas con quesillo, and Peruvian carne a lo pobre, the outlet's report notes. The lineup also includes tortas, grilled chicken plates, chicken wings, chicharrones, Dominican picadera, fried chicken with plantains, pork chops with plantains, and a signature Trío Hamburguesa built with beef, cheese, bacon, and house sauce.
The truck rounds things out with breakfast items, desserts, and drinks, and directs customers to trioresto.com for the full menu and additional information, per the same report. That breadth of offerings — spanning Mexican, Salvadoran, Honduran, Nicaraguan, Peruvian, and Dominican dishes under one roof — sets Trioresto apart from single-country concepts that have become increasingly common on Montgomery County's food truck scene.
Why Gaithersburg Is Fertile Ground for Latin Food Concepts
The multi-national menu isn't a random bet. U.S. Census Bureau estimates show that 30.5% of Gaithersburg's population identified as Hispanic or Latino as of July 2025, up from 28.5% in the 2020 Decennial Census and 24.2% in 2010, according to the U.S. Census Bureau. American Community Survey data from the same agency also shows that 44.3% of Gaithersburg residents are foreign-born, making the city one of Maryland's most multicultural municipalities.
A demographic report from the Montgomery County Planning Department helps explain the specific menu choices. Salvadorans represent the largest specific Hispanic origin group in the county at roughly 35%, followed by Hondurans and Mexicans at 7% each and Peruvians at 6%, per the Montgomery County Planning Department's findings. That breakdown lines up closely with Trioresto's pupusas, baleadas, and carne a lo pobre offerings. Gaithersburg itself has grown into a major suburban hub, with its population reaching 69,657 after the 2020 Census — a 16% jump from 59,933 in 2010 that made it Maryland's third-largest incorporated city behind Baltimore and Frederick, the Census Bureau's figures show.
Part of a Broader Food Truck Wave
Trioresto's debut fits into a pattern of mobile food vendors expanding across the county. Third truck in Derwood was how Hoodline described Tacos El Pariente's expansion earlier this month, when the Mexican street-food concept scheduled the grand opening of its third Montgomery County truck for Monday, October 5, following existing spots in Germantown, Olney, and a storefront in Gaithersburg. Fast-casual Latin dining has also been spreading into vacated commercial space nearby — Hoodline reported that charcoal chicken restaurant Guapo's GO soft-opened on Darnestown Road in September in a space formerly occupied by California Tortilla.
The commercial property at 9426 Stewartown Road, which includes office suites and exterior space leased for food truck operations, last sold for $1.6 million in November 2021, according to real estate records from Compass. Mobile food units in Montgomery County must pass inspection, and permits are renewed by January 31.
It remains unclear whether Trioresto operates under the same ownership as the former Elias Taqueria, what its exact daily hours will be, or whether the operators plan to stay at Stewartown Road long-term or eventually expand to additional locations, following the path taken by other Montgomery County food truck brands.
