How to Make My House Seem Like a Restauraunt?!?

Where i live it has been so warm. I recently got an addition onto my house including an AMAZING rooftop patio. It has a wall fountain a tail area and an area to eat dinner. Although I can't cook that well, I will be basically making dinner for my family tonight (mom dad brother) My mom will prepare everythinhg but I will put everything into the oven and stuff. I really want it to seem like a restraunt so, can someone please tell me what things I can do to make it really seem like a restraunt. Also, please tell me how you guys think i should make the whole evening. Please plan drinks, appetizers, then the meal. Please tell me what to do as the "waitress" for tonight and how to make this night really special! Thanks! Please include anything you want and hurry... dinners in 3 hours!!!
