It is usual to have a salad when an American has his meal. American people eat the salad before the main dish. A nice American thing is the salad bar. In restaurants of salad bars, the waiters do not bring you salad. You go to the salad bar and help yourself, usually eat as much as you want. You eat the salad while some people cook the main dish.

American people know how to choose from the menu (菜单). American menus look different,because they use some unusual words. For example, potatoes most often come to “French fries” or “baked potatoes”. If you order a baked potato, the waiter will ask you want on it. The answer is usually butter or sour cream. Very often, vegetables don't come with the meal, and you have to pay extra (额外的) money for them.

You might hear that in American restaurants, if you can’t finish your meal, you can put the rest in a “doggy bag” and take it home. That means when you leave so ask if you need help to put it into a little bag, or you can just ask him to do this. That’s all about American restaurants. Do you want to enjoy yourselves in one of them.
