What is the difference between hotel and restaurant?

Well, in India there is very small difference between the two. We call it a Hotel where we take food. It is not at all wrong saying that "I am eating now in a hotel" or "Let's have a coffee in the hotel".

But actually when we say Hotel it points to a place where we stays where we are away for any vacations or any business meetings and when we say a Restaurant it is completely a place where we can only take food. No way we can take a full night rest in a restaurant. A hotel can have a restaurant or more than one restaurant within it.
