According to Tom Fitzmorris in his blog The New Orleans Menu, Mandina’s number one for the best oyster-artichoke soup in the area. Check it out! 1. Mandina’s. Mid-City: 3800 Canal. 504-482-9179. Although Mandina’s turtle soup is more famous, its oyster-artichoke potage is better. One of the very best, in fact, with a flavor closer to that of LeRuth’s than any other often available. I wish the Mandina’s on the North Shore had it more often.
