I am surprised by the *very* mixed reviews to be found here and it is very hard to understand why it would be. All one can do is honestly report one's experience and offer any suggestions that might help the diner and the owner. We ate at this restaurant last night. The first thing to say is what a fantastic location. Castelnau is a beautiful medieval village and the square is stunning by both day and night. If you want to eat there you don't have much in the way of choice unless, you want to drive some distance. The only other restaurant is three times the price, it was deserted when we arrived. Des Arcades had two French couples seated there. We ordered from the two very reasonably priced set menus - trout and duck. The service from the young waiter was good. The trout and duck were perfectly cooked and both came with a good quantity of vegetables. At the price, really, impossible to complain about anything. The Gaillac rouge (Rieux) was good. Indeed, given the many, usually disappointing, Gaillac reds I have tried, I'd have to say that it was amongst the best. The deserts were alright, nothing special, but more than adequate. All-in-all, I think the restaurant did well. The staff we dealt with were friendly. Credit where credit is due, I cannot but recommend giving this restaurant a try. It seems to me to be a lot better than some of the reviewers have suggested. Perhaps it is to do with who is front-of-house - the young man we dealt with was great, an asset to the place.
