Just a sandwich? Not at Killer Po Boys, which started as a pop-up and grew so popular they opened this space off Dauphine Street. It's in the heart of the French Quarter, but this spot offers a contemporary take on the classic po'boy. It begins with the bread, sourced from Dong Phuong bakery. Shrimp, seasoned and seared instead of fried, are the heart and soul, while creamy sriracha aioli and a pickled vegetable slaw provide just the right amount of punch. Of course, it's just one of the dozen offerings, which also include barbecue chicken confit, cheddar omelet, and vegetarian options, along with sides like chips and smothered greens. 
As expected, it's a casual, order-at-the-counter kind of place where you'll find bottles of Crystal hot sauce at every table.
