     Eating out is more popular in Britain today than it has ever been. It is reported that British people spend

more eating out than cooking for themselves and eating at home. It seems that many British people are

becoming more and more interested in how good their food tastes, and also how healthy it is.

     However, eating out can also be expensive, so British people do not eat out every night. When having a

date with friends, or having a birthday, many people like to go to a restaurant, and people often also eat in a

restaurant before going to the cinema or the theater.

     As in all cultures, there are many rules of manners about eating. The knife and fork should be used in the

correct way. It is also impolite to speak with your mouth full when you are eating.

    Most British cities have a large collection of food as well as British food, from the very cheap to the very

expensive-French, Italian, Indian, Chinese, Thai, Japanese and many, many more.

     When people are too tired to cook after work, they often get a"takeaway". This means that they order from

a take-out restaurant by telephone, and then go to get it. Many take-out restaurants also send it to your house.

All you have to do is to open the door, pay and eat!
