How a Mexican Chef Built Two Successful Restaurants Side by Side in Texas

Opening one successful restaurant is hard. Opening two right next door to each other takes vision, patience, and a strong sense of purpose.

Chef Juan Ramón Cárdenas has done just that in Fort Worth, Texas. His first restaurant, Don Artemio, opened in 2022 and quickly gained attention for its thoughtful and refined take on Mexican cuisine. In 2025, he expanded with a second restaurant, Dos Mares, located directly beside it.

This was not a rushed decision or a move driven by quick growth. It came after years of research, careful observation, and deep respect for Mexican food traditions.

Seeing Opportunity in Texas

When Chef Cárdenas arrived in the Dallas–Fort Worth area, he noticed something many people overlook. Texas has access to some of the best seafood in the world. Fresh fish and shellfish arrive quickly thanks to major airports, strong transportation networks, and dependable supply chains.

This access changed how he viewed Mexican cooking in Texas. At Don Artemio, he and his son Rodrigo created a sea bass dish served with black mole made from scratch. Guests responded right away. The dish became a favorite and sparked a larger idea.

Instead of following popular seafood trends, Chef Cárdenas asked a simple but important question. How could Mexican coastal cooking be presented with care, depth, and respect while using world-class ingredients?

Building a Concept Before Building a Restaurant

For Chef Cárdenas, a restaurant always starts with a concept, not a menu. A strong concept includes the story behind the food, the values of the team, and the message shared with guests.

Mexico has 17 coastal states, and each one has its own food traditions. Dos Mares was created to reflect this wide range of coastal cooking. The team spent time researching recipes, cooking techniques, and regional ingredients from across the Mexican coastline.

When the space next to Don Artemio became available, it felt like the right fit. Planning began in 2022, with focused development starting in early 2023. The goal was simple. Open only when the concept feels fully formed.

Dos Mares officially opened its doors in 2025.

Two Restaurants, Two Personalities

Opening a second restaurant beside a successful one always comes with risk. Chef Cárdenas admits there was concern that Dos Mares might take guests away from Don Artemio.

The solution was to make the two restaurants connected, but clearly different.

Don Artemio offers a more formal and polished dining experience. Dos Mares feels younger, relaxed, and playful. Both share the same foundation, respect for Mexican culture, high-quality ingredients, and strong service, but each expresses it in its own way.

Instead of competing, the two restaurants support one another. Guests can choose the experience that fits their mood without having to go anywhere else.

Lessons in Leadership and Patience

Running Don Artemio taught Chef Cárdenas valuable lessons that shaped Dos Mares. Even small delays can slow a project by months. Patience matters. Timing matters.

He also learned the importance of teamwork. Dos Mares is a family and community effort. His wife Beatriz, a pastry chef, played a key role. His son Rodrigo works as both engineer and chef. His daughter contributed original artwork to the restaurant. Nearly 60 people now help run both locations.

This shared effort created a strong internal culture, which shows in the guest experience.

Leading With Purpose

In an industry often focused on fast expansion, Chef Cárdenas chose a different path. He focused on research, clarity, and respect for tradition.

Both restaurants continue to evolve through seasonal menus, thoughtful service, and art installations. For Chef Cárdenas, cooking can be more than a task. When done with intention, it becomes an expression of culture.

By building two restaurants side by side, he has shown that growth does not have to dilute quality. With a clear vision, it can deepen it.

A Recipe From the Chef: Caldo Dos Mares

To close the story, Chef Juan Ramón Cárdenas shared one of the foundations of Dos Mares. Caldo Dos Mares is a slow-simmered seafood broth that reflects Mexican coastal cooking at its core. It is rich, balanced, and built with time.
