The Coop's of today is not the same as when it opened 25 years ago. That said, there's no shame in visiting the place now.

When Coop's opened 25 years ago, it was an only-locals place, hidden in what was then a much more secluded and dark end of Decatur St. It was a dive bar when dive bars were less in fashion, and the kitchen would stay open late without a set closing time, continuing to serve food for as long as people would come in and order. So it developed quite a regular following among locals working in the French Quarter who would come in after their shifts in the other restaurants and businesses would end. And the food was surprisingly good for dive bar food and absolutely based on classic New Orleans (mostly Cajun) cooking, even if, like most restaurants, they took liberties. It was so good, in fact, that at some point tourists discovered it and, given the long lines out the door much of the time, I think it now must be written up in most tour books. But that doesn't make it bad. I think the locals have largely fled, and on the rare occasion I still wander in I no longer recognize the staff, whereas in the past I always would. But the food is still pretty decent, and it still remains a solid choice for people looking for something good and relatively cheap in the Quarter. I won't wait in the lines for a table there, but if I wander by and have a hankering, and can snag a seat at the bar, I never object to a meal at Coop's.

One word: uber. Uber works great in New Orleans. Have one (or more) of your meals at the High Hat Cafe or one of the other places outside the Quarter listed up-thread.
