Jack's

Jack's was founded on November 21, 1960, by Jack Caddell (1927–1991) as a single walk-up stand in Homewood, Alabama, a suburb of Birmingham. This location still operates today after several remodels, the most recent in 2019, and is the chain's flagship store.

The original menu featured items such as fifteen-cent hamburgers and fries, twenty-cent shakes, and a twenty-cent "Fish-On-A-Bun." By the mid-1960s, they had more than a half dozen locations in the Birmingham metro area: the original Homewood store, Roebuck, 3rd Avenue West, Bessemer, Five Points West, Vestavia, Eastwood Mall, Alabaster and Center Point, and additional stores as far away as Mississippi, South Carolina, and Gatlinburg, Tennessee. Jack's was one of the first fast-food chains to market to children, heavily sponsoring local programming such as "The Popeye Show".

In the mid to late 1970s, Jack's was expanding into south Alabama and the Florida panhandle. In the 1980s many of these locations began to close, but at least one individual was having success with Jack's. Benny LaRussa, primarily involved in the grocery business with Bruno's grocery, had purchased a single franchise in the 1960s. In 1979, LaRussa abandoned groceries and purchased a franchise territory of 13 Jack's stores. From then until 1988 he expanded his territory to 33 stores. Then, in 1988, LaRussa purchased the total franchise rights to the Jack's concept. In 2015, Jack's was acquired by a fund managed by Onex Corporation, a private equity company based in Toronto, Canada.

On July 25, 2019, Onex announced that it had reached a deal to sell Jack's Family Restaurants in a deal expected to close in the third quarter of 2019. The deal finally closed in August 2019. Onex did not disclose the buyer or financial terms of the deal, but Restaurant Business Online reported that AEA Investors, a private equity firm based in New York, is the buyer of the restaurant chain.

Jack's specialty is its breakfast. Biscuit sandwiches are the predominant breakfast item, including the smoked sausage, country ham, egg, cheese, bacon, sausage and country fried steak options. Jack's also serves pancake breakfasts, wraps, and a variety of sides, such as hash browns, grits, and gravy. For lunch and dinner, the signature item is the Big Jack, a double patty cheeseburger with lettuce, onions, tomato, pickles, mustard, ketchup, and mayonnaise. The lunch and dinner menu also includes a variety of side items, including French fries, coleslaw, green beans, mashed potatoes and biscuits. They also offer boneless chicken tenders which are served with a variety of dipping sauces, bone-in fried chicken plates, fried and grilled chicken sandwiches, and a number of salads which can be topped with either grilled or fried chicken. Desserts include their signature fried pies, hand-spun milkshakes, and ice cream. Seasonal and limited-time offerings also appear on some menus, such as lemonade shakes and the Mushroom & Swiss Burger.

In 2026, Jack's added a Conecuh sausage dog to their menu.
