When you get to a restaurant, the waiter will ask you what you want.

The waiter may speak to you casually, because you're young:

 English Spanish 
 What do you want to drink? (casual) ¿Qué quieres beber? 
 What do you want to eat? (casual) ¿Qué quieres comer? 

The waiter may speak to you politely, because you're a customer:

 English Spanish 
 What do you want to drink? (polite) ¿Qué quiere beber usted? 
 What do you want to eat? (polite) ¿Qué quiere comer usted? 

You can answer three ways:

 English Spanish 
 I want to eat  _____, please. Quiero beber  _____, por favor.
 I want to drink  _____, please. Quiero comer  _____, por favor.
I want  _____, please.    Quiero  _____, por favor.

Then you say gracias when the waiter - el camarero or la camarera - brings your food.

 English Spanish 
please por favor
 thank you gracias
