Restauration means catering. This means that you won't get any meal with the night.
Usually, you can have the following :
- Breakfast (petit déjeuner in French)
- Half board (demi pension in French, which usually mean that you have lunch or diner included)
- Full board (pension complète in French, which means that you have breakfast, lunch and diner included)
So in that case, I think they used "restauration" as a poor direct translation to express the fact that there is no meal included. So probably, the breakfast is also excluded. If you provide the hotel name, I can check the french part and tell you for sure.
