Dat Dog, a New Orleans-based restaurant that sells a variety of upscale hot dogs, is looking at opening locations in Baton Rouge and Hattiesburg, Mississippi.

Owner and co-founder Constantine Georges said he’s looking for the right place in each city to put a Dat Dog. He’s the brother of John Georges, The Advocate’s publisher and CEO.

“We’ve looked at several places in Baton Rouge, but we haven’t found the right fit yet,” he said. “We’re looking for a good fun place for people to come.”

In Hattiesburg, Georges said he’s looking for locations around the campus of the University of Southern Mississippi.

The first Dat Dog opened inside a glorified shed on Freret Street in New Orleans in 2011, the same year that street bloomed into a restaurant row. The concept took off quickly, and the restaurant soon moved to a larger location just across the street. Additional Dat Dogs followed, on Magazine Street in 2013 and Frenchmen Street last year. In March, Dat Dog opened a fourth location in the food court at Lakeside Mall.

“All of our locations have been successful and part of that is we took our time to think it through,” Georges said.

Dat Dog sells hot dogs with a variety of meats, from traditional beef and pork wieners to crawfish, alligator and turducken sausages.
