We rented an apartment in Carcassonne recently, and previous guests had recommended La Sixieme Sens in the comment book. Obviously, we had to try it out and I'm pleased to say that it was worth the effort involved in finding it! It didn't help that the road was uprooted at the time, full of diggers and other paraphernalia!
For anyone looking for rough directions, if you walk from Place Carnot in the opposite direction to the canal and the railway station, it is a couple of streets down, and you need to turn right when you come to Rue Aime Ramond. It's just a few doors up on the left after that!
There are a few tables on the street level where the bar and kitchen are located, but the majority of tables are in the cellar underneath, and this adds greatly to the atmosphere of the place.
The waiters were very friendly and helpful, and they did their best to explain everything on the menu so that we could make an informed choice.
Food was reasonably priced, varied and of excellent quality (as were the wines) and we both agreed that it would be on our list of places to return to should we be fortunate enough to find ourselves in Carcassonne again.
