The Spirit of the Back Bar: Agave in the Inland Empire

Mexican restaurants in the United States have undergone a significant shift in how they approach spirits. A decade ago, the back bar at most regional cocinas meant a handful of mass-market tequilas and a domestic beer cooler. That has changed, and the change is most visible in communities with deep ties to Mexican culinary culture, where the demand for mezcal, sotol, raicilla, and artisanal tequila comes from guests who understand the categories from both sides of the border.

The agave spirits category rewards the kind of curation that reflects genuine sourcing knowledge. Single-village mezcals, ancestral production methods using clay pots or underground ovens, small-batch expressions from producers in Oaxaca, Durango, or Guerrero , these are not interchangeable products, and the gap between a thoughtfully assembled agave program and a generic tequila shelf is as wide as the gap between a wine list with regional depth and one built around brand recognition alone. Bars in other American cities have moved this conversation forward: Superbueno in New York City has built its agave program around Mexican regional identity, while Julep in Houston and Jewel of the South in New Orleans demonstrate how regional spirit traditions can anchor a serious drinks program. Kumiko in Chicago and ABV in San Francisco show how category depth translates across different culinary formats. For Mexican restaurants in the Inland Empire, the question is whether the kitchen's regional fidelity extends to the bar.

Ontario, as a city with a significant Mexican-American population, is a logical place to expect that extension. The cultural infrastructure , the knowledge, the demand, the supply chain , is present in a way it isn't in many American cities. Venues like Bar Leather Apron in Honolulu, Allegory in Washington, D.C., and Bar Kaiju in Miami illustrate how seriously the current generation of American bars is treating spirits curation as editorial content, not afterthought. The Parlour in Frankfurt on the Main demonstrates the same instinct operating internationally. The standard is high, and the expectation that a Mexican restaurant in 2024 should know its agave as well as its mole is a reasonable one.

Euclid Avenue and Its Dining Neighbours

Ontario's Euclid Avenue carries a different dining character than the city's newer commercial strips along Haven or Milliken. The street has older bones and a more settled, community-serving function. Gloria's Cocina Mexicana at 401 N Euclid Ave is in that older urban fabric, near other independently operated restaurants that have served the neighbourhood for years rather than months. It shares a city with Vince's Spaghetti Ontario, a long-established Italian-American address that speaks to the Inland Empire's layered immigrant dining history, and Zeke's Eatin' Place, another local fixture that operates outside the attention economy. Together, these venues sketch an Ontario dining scene that is more durable than it is fashionable, which is not a criticism.

The broader Ontario context for visitors: the city sits roughly 35 miles east of downtown Los Angeles, served by Ontario International Airport (ONT), which makes it a practical base for Inland Empire travel without the distance penalty of driving from LAX. The dining options around N Euclid Ave are walkable or short drives from central Ontario, and the area rewards exploration over itinerary-building.
