　　Do you like to eat out? Do you like to eat quickly? Do you like expensive food?

　　Some people go to fast­food restaurant for these reasons. In the past, people usually went to diners (路边餐馆) for these reasons. In fact, many people in the states still go to diners today for the same reasons.

　　A man named Walter Scott had the first "diner" in 1872. It wasn't really a diner. It was only a food cart (手推车). People on the street walked up to the carts to buy food. These carts served late night meals. The meal was a sandwich or boiled eggs. In 1887, Samuel Jones built the first diner big enough to allow the customers to come inside. However, they didn't sit down, later people built diners with counters and stools, and people sat down while they ate.

　　Before long many diners stayed open around the clock. In other words, people were able to eat in a diner at any time. Diners changed in other ways, too. The original menu of sandwiches and coffee became bigger. It included soup, favorite dishes, and a breakfast menu. In addition, diners soon became permanent buildings. They were no longer carts on wheels.

　　Diners today look similar to the diners of the early 1990s. They are usually buildings with large windows. Inside, the diners have shining counters with stools, booth (公用电话), and tables and chairs. People can have all three meals in a modern diner.

　　Today, many people eat in fast­food restaurant such as McDonald's and Burger King. However, the diner remains an American tradition, and thousands of people still enjoy eating there. It was popular a century ago, and it is still popular today.
