🥩 Whole-animal butchery & dry-aged in-house. Dry-aging concentrates beefy, umami-rich flavors while also breaking down protein fibers creating a more tender steak.
Delicious beef, tasty veg, and great bourbon and wine programs are coming to Mill Iron 4 soon! Stay tuned, yall.
🥩 I hopped in the butcher room with Mill Iron 4 butcher & owner Dustin Olsen while he cut, trimmed, and portioned steaks for our first mock service.
Dustin spent months researching and driving around the state to find the best beef raised in the best ways. And it’s beautiful.
Mill Iron 4 will work with a rotation of ranchers and farmers from Kentucky and Indiana. We’re buying whole sides of beef, butchering, aging, cutting, and trimming all in house for your plate.
Expect the big primals, but don’t miss the flight of rare cuts that typically get tossed into ground beef or saved for the butcher’s, themselves.
We can’t wait to see you.

Before the dinner bell rings and Louisville's hottest new steakhouse fills up, open the silver hinge of the backyard meat locker to find a smiling, apron-wearing Dustin Olsen.
He's happy alone and in the cold of this little fridge box, surrounded by a cleaver and handsaw and hanging chunks of beef carcasses and just steps away from his cowboy-meets-posh restaurant. Olsen opened Mill Iron 4, 1758 Frankfort Ave., in early February and it's already a top hit on the list of 2026 newbies to Louisville's restaurant scene. The butcher and pitmaster "got obsessed" with beef butchery during his time learning the cuts at Red Hog, regarded as the area's first craft butcher shop.
Part of Mill Iron 4's early success is a play on the rising trend of culinary flights. Searches for food flights were on the rise by up to 400%, in 2025, according to Yelp and local examples include a build-your-own deviled egg tray at The House of Marigold and the Souper Fecta flight at Crave Cafe.
Mill Iron 4 has its own upscale spin in the form a $129.99 steak flight, which features three 6-ounce samples of rare steak cuts, presented as a beautiful feast in a silver tray.
