Dat Dog is venturing outside of Orleans Parish for the first time.

A new location in Lakeside Mall in Jefferson Parish, opening Sunday, will be Dat Dog’s fourth, joining its Freret, Magazine and Frenchmen Street locations.

Founded in 2011, Dat Dog is a New Orleans hot dog joint specializing in gourmet sausages and wieners.

Dat Dog’s Lakeside offerings will include many menu items available at other locations, as well as a new combo meal, a first for the restaurant group, that will include a hot dog, fountain drink and Dat Dog’s fries.
