Which is the oldest continuously run restaurant in New Orleans, established in 1841?

Antoine's Restaurant holds the distinction of being the oldest continuously operating restaurant in New Orleans, having opened its doors in 1841. This historic establishment is renowned not only for its age but also for its significant contributions to the culinary landscape of the city. Over the years, Antoine's has served numerous influential figures, including various U.S. presidents and celebrities, cementing its status as a cornerstone of New Orleans gastronomic heritage.

The recipes and traditions developed at Antoine's have helped shape Creole cuisine, showcasing the restaurant's integral role in the city's cultural tapestry. The restaurant continues to thrive today by maintaining its original charm while adapting to contemporary dining trends, making it a popular destination for both locals and visitors.

In contrast, the other venues listed either do not have the same historical significance or were established later, which disqualifies them from being the answer to this question. Each of these establishments has its own unique identity and contributions to New Orleans' food scene, but none can match the legacy and longevity of Antoine's Restaurant.
