John Currence was born and raised in New Orleans, Louisiana to a family that loved to cook and spend time in the kitchen. His mother's travels with his father during childhood, combined with the family's several years in Europe, brought the dishes of the world to their dinner table, while time spent hunting and fishing in South Louisiana began the education in the foods of his home.

Currence's first cooking job was while working offshore as a deckhand on a tugboat in the Gulf of Mexico, though he saw his first restaurant job while in school at UNC where he started washing dishes at Bill Neal's Crook's Corner. He worked his way up through the Crook's kitchen and after three years, Currence returned to New Orleans at the behest of a high school friend, Larkin Selman, to open Gautreau's where he worked as Selman's sous chef. After several years, Currence moved on to the Brennan family of restaurants to help open Bacco before finally settling in Oxford in 1992 and opening City Grocery.

Since then, the City Grocery Restaurant Group has seen a number of openings, including Nacho Mama's, Kahlo's, Ajax Diner, City Grocery Catering Company, Boure, Snackbar, and Big Bad Breakfast.

Big Bad Breakfast is located off of Highway 280 in Birmingham
