The menu reads like a burger lover’s fever dream—from classic smash burgers to wild creations featuring bourbon bacon jam and key lime datil aioli.

The team takes pride in their craft, seasoning simply and pressing perfectly to let the quality beef shine through.
Tar Heel Signature Burger: North Carolina Pride on a Bun
This signature creation packs mustard, onion, grandma’s chili, and southern slaw onto a perfectly pressed Angus beef patty for an “all-the-way” experience. The combination sounds chaotic but works beautifully—the tangy slaw cuts through the rich chili while mustard and onions add sharpness.
Customers consistently name this among their favorite menu items, praising the balance of flavors that pay homage to classic Carolinas-style burgers. The chili (no beans, thankfully) adds substance without overwhelming the beef, while that southern slaw brings a refreshing crunch to every bite. This isn’t your typical burger—it’s a regional specialty that transports taste buds straight to the Carolinas. The portion size means you’re getting a meal that satisfies without breaking the bank.
Hurricane Burger: Weather the Storm with Mac and Cheese
Prepare for a flavor hurricane with this beast featuring white American cheese, grilled jalapeños, white cheddar mac, crumbled bacon, and spicy chipotle sauce. Yes, you read that right—they put mac and cheese directly on the burger, and it’s absolutely brilliant.
The grilled jalapeños provide heat that’s tempered by creamy mac and cheese, while bacon adds that essential salty crunch. Reviews rave about this indulgent creation, with diners describing it as “smokey, meaty and rich” with a sweet and spicy finish. The spicy chipotle sauce ties everything together without overpowering the quality beef underneath. This burger represents everything great about creative comfort food—it sounds ridiculous until that first bite proves the genius. 🌪️
Black Mountain Signature Burger: Mushroom Lovers’ Dream
For those who appreciate earthier flavors, this baby swiss, mayo, grilled onion, and baby bella mushrooms combination delivers sophistication without pretension. The baby bellas get grilled until golden and caramelized, developing deep umami flavors that complement the beef.

Customers praise this burger for its “so good” factor, with the grilled onions adding sweetness that balances the savory mushrooms. The baby swiss melts perfectly, creating a creamy blanket that holds everything together.
