Few of us have the capacity to truly reinvent ourselves. Gus Reckel, the owner-baker behind L’Imprimerie, seems to be one of those few. Before opening his Bushwick coffee shop and bakery last summer, the Frenchman had a nearly 20-year career as an investment banker, working in Paris, Zurich, and London until finally landing in New York three years ago. Later, he left to study the craft of baking, grew a long beard, and opened his own boutique bakery in a former print shop under the M train tracks.
