As I already commented, in three areas I lived and enjoyed the Valley of Arán for some time and because of the location of my house, I went by and stopped in Eth Bot every day.
It is located in the square of Salardú, facing its famous sculpture of a boar. The outside is that of an ancient Aranese house and when crossing its threshold, offers the real sensation of being in one of them but with counters and waiters.
The food I recommend is its meats and once evening falls, the locals of the area would come together here (monitors, ski staff, etc.) and after dinner if things haven´t changed a lot, you will have a pleasant place for enjoying some drinks.
