Big Bob Gibson Bar-B-Q

Decatur, Alabama has been a barbecue pilgrimage site for a century now, and it all traces back to a hand-dug pit behind a house near the Southern Railway line. In 1925, a burly L&N railroad worker named Bob Gibson started smoking pork and chicken on weekends for friends and neighbors, cooking over hickory coals in brick pits he built himself. A friend, Roslyn Mitchell, is said to have told him his future was not in the railroad but in barbecue. He listened, and Big Bob Gibson Bar-B-Q has been feeding Decatur ever since.

What set Big Bob apart from the start was a thin, peppery, mayonnaise-based white sauce he mopped over smoked chicken, a condiment that did not exist in barbecue country before he invented it. It became the restaurant’s signature, and it has since spread across the South and beyond as “Alabama white sauce,” showing up on menus far from the Tennessee River. In Decatur, though, it is still ladled the original way, straight from a dipping pot onto pulled chicken pulled hot off the smoker.

The restaurant has stayed remarkably close to home. All five of Bob Gibson’s children went into the family business by the 1950s, and his daughter Catherine and her husband Coy McLemore added homemade pies and potato salad to the menu, dishes that are still on offer today. Ruth Hopkins and Bob Gibson Jr. opened a second Decatur location under the name Little Bob Gibson Bar-B-Q, while another branch of the family carried the recipe to Huntsville in 1956. Grandson Don McLemore and his wife Carolyn ran the operation through the 1970s and 80s, building a new facility in 1987 that could handle catering for thousands of guests at once.

The fourth generation arrived in 1992 in the form of great-granddaughter Amy and her husband Chris Lilly, who has since become one of the most decorated pitmasters in the country. Under his hand, the restaurant’s competition team has won ten state championships and ten world championships, and its red sauce was named the best sauce on the planet at the American Royal contest. The white sauce, meanwhile, is now bottled and sold in thousands of grocery stores across multiple states, though the version served at the restaurant’s own counter is the one worth the trip.

Today the family still operates two locations inside the Decatur city limits, one on 6th Avenue Southeast near U.S. Highway 31 and a second on Danville Road Southwest, both open seven days a week for dine-in and drive-through. Regulars order the smoked chicken with white sauce, but the pulled pork holds its own, piled high with the smoked meat’s bark still crisp at the edges. Sides lean traditional Southern, turnip greens, mac and cheese, and a barbecue-stuffed potato so large it has been jokingly compared to a warship, plus a rotating selection of Catherine McLemore’s original pies for dessert.

Visitors planning a stop should expect a working barbecue joint rather than a fine-dining experience: counter ordering, picnic-style seating, and the smell of hickory smoke that clings to the parking lot. Catering is a serious part of the business, handling everything from small family gatherings to large public events, and the restaurant ships its sauces and rubs nationwide for anyone who cannot make the trip to north Alabama in person.

What makes Big Bob Gibson worth seeking out is less about novelty and more about continuity. Five generations of one family have kept the recipes, the pits, and the town the same, even as the white sauce they popularized has become a fixture of barbecue menus everywhere. For visitors exploring Decatur’s riverfront and downtown historic district, a plate of smoked chicken here is as close as the city comes to a required stop, a century-old institution that still runs on family recipes and hickory smoke rather than any corporate playbook. Locals tend to have strong opinions about which of the two Decatur locations they prefer, but both draw from the same pits and the same white sauce recipe that started it all on a sycamore tree table nearly a hundred years ago.
