the english like what they call "good plain food". usually they like steak, roast beef, yorkshire pudding, and fish and chips.

dinner is the most substantial meal of the whole day. it is usually eaten at 7 o'clock.

the first course may be soup (though the english don't like it very much).

the main course will often be fish or meat, perhaps the traditional roast beef of old england, and a lot of vegetables.

the, next course will be something sweet and often baked, such as a fruit pie. last of all there may be cheese, often with biscuits.

it is common knowledge that the english are very fond of tea. they like to have "a nice cup of tea" 6 or 8 times a day, sometimes even more.
