Relax and Refuel After Your Black Hills Adventure

Miner

The family-friendly Big Thunder Bar & Grill is your one-stop-shop for fantastic fresh local cuisine, cooked to perfection morning, noon, and night in Keystone, South Dakota. Just steps away from the excitement of Big Thunder Gold Mine, the Big Thunder Bar & Grill is equally as golden with ample seating, high-quality service, and an authentic menu featuring locally-sourced game provisions and fresh ingredients.

Whether you’re looking to start your busy day in the Black Hills sunny side up or are looking to wind down after a day of traversing the far reaches of the hills, our game restaurant has the right variety of food and welcoming ambiance to make your dining experience exceptional.

Our spacious outdoor deck and outdoor stone fireplace is perfect for those warm summer days and cool evenings that the Black Hills region is known for, with an interior that is just as welcoming. You haven’t had a taste of the Black Hills until you’ve eaten at Big Thunder Bar & Grill.

The Big Thunder Bar & Grill is open by reservation only during the months of March and November, while our hours mirror that of the Mine during the tourism season from April through October.
