I've had a look on their website and it all looks excellent but I was thinking more of a good bistro, something a little less formal. Don't forget I'll have spent the previous four nights in a tent and will be replete with a large rucksack. I don't want to offend the other diners!!!
Don't worry Steve, it's not a formal restaurant at all and if you're worried about the "odeur de camping" that might surround you after your stay on Houx, they have a sunny terrace where you can have lunch also.
Ohh and yes they are open on Monday.
