What's the difference between a hotel and a restaurant?

Actually, it's all the same, except that the hotel is bigger than the hotel. Even if the hotel is luxurious, it can only be operated without catering, but the hotel is different. It can operate open things with large-scale luxury settings, but in many places we can see that their levels are different. Why not make a good hotel a few stars instead of a few stars? Just like the generation gap between restaurants and restaurants!
