Born in the Heat of ATX.
In a city known for its world-class food scene, Suns Out Buns Out was born from a simple mission: to create a burger that works as hard as you do. We believe that a great burger isn't just a meal—it’s an experience. That’s why we obsess over the details, from the perfect sear on our premium beef to the soft, toasted buns that hold it all together.
Our story is rooted in the vibrant spirit of Austin’s West Campus. We wanted to build a place that reflects the city’s laid-back yet ambitious personality. At Suns Out Buns Out, we don’t do "ordinary." We do bold seasonings, fresh-cut toppings, and a atmosphere that feels like a backyard hangout with your best friends. We’re proud to be a part of the 512 community, keeping Austin fed and happy, one bun at a time.
Located at 2512 Rio Grande St, right in the heart of Austin’s vibrant West Campus, Suns Out Buns Out Burger Company is more than just a food truck—it’s a local favorite for anyone craving a bold, juicy, and authentic Austin burger experience. Whether you're a UT student pulling an all-nighter or a traveler looking for a taste of the 512, this is where the sun shines brightest on your plate!
Suns Out Buns Out takes pride in serving handmade patties and creative combinations that hit the spot every time:
Traditional Flavors: You can never go wrong with their Double Burger, featuring two freshly pressed beef patties, melted American cheese, and classic toppings on a perfectly toasted bun.
Signature Hits: * The SOBO Special: Their crown jewel! A unique mix of a beef patty, grilled chicken, and crispy bacon, typically served on a sweet Hawaiian bun with Pepper Jack cheese and their secret "Greenbelt Sauce."
The Rio Melt: A local nod to its street address, served on buttery Texas Toast with double beef, pepper jack, grilled onions, and savory Rio sauce.
The West Texas: For those who love a smoky kick, this one comes with BBQ sauce, fried onions, and "Dojo Mustard."
Outdoor Energy: Operating as a food truck in a lively student hub, the vibe is casual, high-energy, and unmistakably Austin. It’s the perfect place to grab a seat at a nearby picnic table and soak in the city’s atmosphere.
