The restaurants of a hotel belongs to food and beverage department. It's totally different department from room division which controls just quality of the f&b work. The f&b department depends on a rooms division but has its own structure with a common spends: Restaurants (the hotels normally have few): Cost on food, cost on beverage, operating equipment and entertainment which normally also belong to f&b.

Sorry I am not from F&B but this is operation work. You can decide spends of restaurant from f&b dep and also from all the hotel operation because restaurant I depending on hotel part
