Harrah's in New Orleans is unquestionably one of the nicer hotels in the area. The staff is very friendly and helpful, grounds are immaculate, and it is in a convenient location to other attractions. The rooms were spacious and very clean. They are soundproofed nicely and the housekeeping staff was undetected. The casino is larger than you probably think and there is a cool bar called Masquerade that is a must-see. The buffet was nothing too special and the selection was limited. The seafood place (Acme) in the casino is quite delicious. If you are in the mood for true authentic food, take the 2 block walk to Mother's which usually has a line out the door.
Overall, a great stay and value and I wouldn't hesistate to come back.
