What's the difference between hotels, restaurants, food stalls and restaurants?

Actually, it's the grade. What about the hotel? High-grade, pay attention to ostentation and extravagance, in fact, everything is flashy; Hotels are actually similar to hotels, except that some of them are listed as stars; Food stalls are different. Pay attention to the atmosphere, whether the food is homely or not, so if it is not very formal, it is actually more interesting to eat in food stalls and restaurants!
