For over 20 years, Ácenar has been welcoming hungry locals and tourists to dine on modern Tex-Mex with a margarita in hand overlooking our quiet slice of Riverwalk.

Another reason to visit Ácenar, HotMex CoolBar is our stunning atmosphere.

More than two decades ago, we took a chance on an empty concrete box tucked beneath the brand-new Hotel Valencia. At the time, this stretch of the San Antonio River Walk had no restaurants, just potential. Inspired by the hotel’s bold interiors, designed by famed Los Angeles modernist Mitchell Dodd, we envisioned a restaurant experience that would awaken the senses and reimagine what River Walk dining could be.

Our mission was clear: create a place where space and flavor collided, offering a fresh take on regional Mexican cuisine rooted in Tex-Mex traditions. We drew inspiration from iconic designer Alexander Girard, whose 1960 restaurant La Fonda del Sol in New York City revolutionized the industry. That spirit of color, creativity, and cultural homage became the foundation for Ácenar’s beautifully designed space.

With the help of Kell Muñoz Architects and Leslie Fossler Interiors, our vision came to life. A dramatic staircase connects the vibrant, disco ball-lit HotMex CoolBar to a spacious dining room layered with Latin-inspired colors, custom woodwork, and stunning views of the River Walk. Bold, modern, and undeniably fun, the two-story space invites guests into a unique world of contemporary Mexican cuisine and playful modern design.

Behind the concept were some of San Antonio’s most notable tastemakers: restaurateur Lisa Wong of Rosario’s, acclaimed modernist English born Chef Bruce Auden of Biga, and hospitality entrepreneur Pete Selig. Together, they created an inventive menu and atmosphere that elevated Ácenar from a simple Tex-Mex restaurant into a River Walk icon.

Since opening in February 2005, Ácenar has helped shape the landscape of San Antonio River Walk Mexican restaurants. Today, we continue to honor that legacy by offering bold flavors, vibrant ambiance, and a dining experience that’s anything but ordinary.

​At Ácenar, we pride ourselves on delivering an elevated, yet approachable dining experience that blends contemporary Mexican cuisine with the rich cultural heritage of San Antonio’s River Walk. Our success is driven by a dedicated team of professionals who bring passion, expertise, and innovation to every aspect of our restaurant.​

Together, our team at Ácenar strives to provide the best in all aspects of hospitality. Whether you’re seeking a vibrant bar scene, private dining options with a view of the River Walk, or simply the best Mexican food in downtown San Antonio, we invite you to join us and savor the flavors that make Ácenar a standout destination.
