One thing Britain is famous for is pubs, and no trip to the UK would be complete without a visit to one of the thousands of pubs across the country.

Pubs play an important role in the social structure of the country. They are places where all ages and social classes mix to talk, do business, or just spend a couple of quiet hours before heading home in the evening.

There are many different types of beer available in pubs. Traditional British beer is called bitter or ale, and is usually served at room temperature. As a result, the British are famous for their “warm beer”! If you prefer a cold beer, ask for lager. This beer is a light yellow in color whereas(而) bitter is a darker brown. All beers are served as pints(500ml) or halves(250ml). To order, you need to ask for a pint or half, and then name the beer. So, you could say, “__________.”

Wine, red or white, is normally available in all pubs, as are spirits such as whisky, gin or vodka.

It is not, however, necessary to drink alcohol. Non-alcoholic drinks are called soft drinks. You can have juice, lemonade or cola, among others.

If you visit a pub in a group, it is important to pay for your “round”. This means that you buy a drink for everyone in your group. Not buying your round is a big social mistake! Remember that you need to order and pay for your drinks at the bar.  

So, follow these tips if you want to get the most out of visiting a pub, and, “cheers!”
