The atmosphere is really very romantic, I strongly recommend it to loving couples.
The fondue is the best in briancon. The amount of cheese was so large, there was so much bread and delicious meats that we couldn't even finish our meal! Moreover, it's cheaper than in the nearby L'etage. And I am really surprised this place has such a low rating. Definetly underestimated.
The owners were very polite and nice even though we couldn't speak any French :)
