It's on Decatur St. by Ursulines, place looks like a dump from outside but the food is great
Here the review from Fodor's = pretty accurate
Casual drinking and supping, Louisiana style, is the order of the day at Coop's. The po'boys and gumbo, available into the wee hours, are some of the best found in the Quarter; a selection of 20 bottled beers and six on draught complement whatever you're having. A crankin' jukebox and popular pool table round out the laid-back bar experience.
Definitely worth a stop, I have lunch there when I'm N.O., Gumbo is different every time I have it there
