First of all, whether a hotel restaurant does good or bad business depends on the following aspects.
First, location, if the location is well chosen, such as: station, shopping malls ...... busy areas, so the business will be very hot. After all, the traffic is huge.
The second is the level of the chef. If the chef cooking is more general, guests come to eat once, will feel that the dishes here are too general, so the restaurant business will be good to nowhere.
Thirdly, it is the owner's behavior. If the boss is more polite, the guests came to the guests on a free dish, or say some good words, people will be very happy, but also from time to time to come to your restaurant, so it will keep the old guests.
Comprehensive above, the restaurant business is good or bad, the main location. The chef, the owner is secondary!
