This really depends on what you are looking for. I adore Clancy's but you have to be in the mood. It is different from Arnaud's and certainly has better food. It is a bit similar to Galatoire's in that it is loud and bawdy. Expect a lot of noise at Clancy's with groups of 5 or more drinking too much, table hopping, and waving to one another across the room. It is the closest thing to a private club you will see and generally people dress up. If you want a quiet, intimate dinner with good food this is not your place. On the other hand, if you went to August, you would be with every business account tourist in the city also, so you would not necessarily sample local color. If you do want a quieter place with local food, try Gautreau's, Upperline, Brightsen's, or Martinique. All of these are in the same general area as Clancy's. Good luck.
Ate an early dinner (only 6:30 reservation available) last month. We were seated upstairs and were plagued by fruit flies. Waitress apologized stating this was an ongoing problem but the flies miraculously disappear by 7 (they did!). My softshell left me longing for the one at Brigtsen's (which he doesn't have often enough). Corn and crab bisque was mediocre. Oysters with brie were delicious ,but very easy to duplicate at home. Except for the flies, not a memorable meal.
