Copeland's traditional downfall is when he can no longer be hand's on in the restaurant. Beyond Copeland's itself (which gets bad the further away from NOLA you get), Popeye's had the same problem -- great in NOLA, progressively worse outside the city.

Another "Find Dining" experience would be the Brennan Family of NOLA. With Commander's Palace, Brennans, The Palace Cafe, Dickie Brennan's Steakhouse, and one or two others, plus locations in Houston, LAX, and LAS for various restaurants.

Note: I know that there are actually two "Brennan's" out there with different oweners. The fact is that they both grew up in the same house, and they both are specialists in Cajun and French Cuisine.
