As you might expect from a New Orleans–inspired restaurant—the name comes from the date of the Louisiana Purchase—the menu includes fried oysters, jambalaya, Cajun-style catfish, and, at lunch, po’ boy and muffuletta sandwiches. To drink, you might have a pint of Abita, a Hurricane, or a Sazerac. And then there’s the decor: Artist Uri Aran has crafted a hothouse vibe, with bold floral wallpaper, a checkerboard floor, tropical plants, and quirky objects—such as vintage editions of Clue and Candy Land and old Johnson & Johnson first-aid kits in the restrooms—from his own collection. Because you can’t conjure up New Orleans without the right music, 1803 will also have a jazz club on the lower level. (They’re shooting for an October opening.)
