Most burger spots stick to basic builds. Carolina Jax on Oak Street turned Jacksonville into a smash burger laboratory, blending Carolina flavors with Florida heat in ways nobody saw coming.
This former food truck now slings onion-smashed patties, pulled pork stacks, and loaded fries from a cozy Riverside counter that feels more like a neighborhood secret than a chain.
It’s the kind of place where one Tar Heel Burger has you texting friends mid‑bite about your next visit.
How they won locals’ hearts
Carolina Jax started as Cackylacky’s food truck, earning “Best Burger in Jax” from First Coast News and competing in Rachel Ray’s Burger Bash before landing their permanent Oak Street spot.
They mastered Oklahoma‑style onion smashing, thin onions cooked right into the patty with mustard, then layered on regional riffs like roasted poblano mayo, datil sauce, and bourbon bacon jam.
Yelp reviewers call the Tar Heel Signature Burger “all that” with sharp cheddar, bacon, pulled pork, and onion rings, while Burger Beast named the patty melt one of 2021’s best bites.
The Hurricane Burger double patties, mac ‘n’ cheese, jalapeños pack enough punch to justify its hype, and loaded fries like Bacon Bacon Ranch keep groups ordering family‑style.
