I feel like a list of places that no one should set foot in would be helpful to visitors. I don't mean a place with a good reputation where you happen to have had a singular bad experience: Every decent or even excellent restaurant can have an off night and frankly, sometimes a bad experience is as much the diner's fault as the business. I'm talking about places that straight up don't give a sh*t about their food, their customers and, frankly, their hygiene.
My top pick it PERE ANTOINE'S (not to be confused with the classic Antoine's, although P.A. would certainly like you to!) On an earlier trip we were exhausted and dazed after a swamp tour and just wandered in there for dinner based on the lovely facade. What we discovered was a disgusting pit of improperly cooked food and dirty tableware. Granted, the Keno machine in the front room should have been a sign to leave immediately but we were exhausted. Since the outside has a nice architecture it's a magnet for tourists who haven't done their homework. Also, I think ghost tours and stuff stop there for drinks. I'll actually steer people away if I see them standing outside looking at the menu. Just awful. I wish Gordon Ramsey would set that place straight but I doubt the owners would care.
