Engineered for Speed. Crafted for Maximum Sear.

Live smash burgers, cooked to order at your venue.

We believe great burgers shouldn't be sitting under heat lamps or sitting in delivery boxes. We bring a commercial live-cooking setup directly to your venue, smashing fresh 80g beef patties to order right in front of your guests.

By combining high-heat searing techniques with our custom Kitchen Display System (KDS), we eliminate long lines while delivering crisp, lace-edged patties, juicy centers, and pillowy toasted brioche every single time.

Our Three Non-Negotiables

  • A cook wearing a black glove pressing thin beef patties on a dark steel flat-top griddle

    The 80/20 Smash

    Premium ground beef pressed hard onto high-heat steel to create a deeply caramelized, savory crust that seals in natural juices.

  • A spoonful of creamy orange burger sauce above a metal bowl on a charcoal-black surface

    The Signature House Sauce

    Our custom 50/50 blend of tangy burger sauce and rich chili mayo—delivering a creamy, zesty finish balanced for guests of all ages.
