I invited my friends for dinner. I prepared a lot of foods for them.
Now, all friends came and we are about to have dinner.
In this situation, I want to say like those
"Enjoy dinner.", "Eat whatever you want.", "Eat as much as your stomach size.", "I don't know you like the foods I made, but I want you to like that and enjoy." (These are correct?????)
I just want to make a comfortable atmosphere and I want my friends to like the food I made and enjoy.
So my question is how I can say when beginning dinner. I want to know common expressions using in English countries.
