Pubs mostly have a large selection of just different kinds of beer, some wines, and cider. Because of its full menu, a pub generally allows minors if accompanied by an adult. Bars specialize in liquor rather than food and tend to offer a wide selection of cocktails, in addition to usual alcoholic beverages.
A pub is unlike a restaurant – you have to go up to the bar to place your order. The signal to show that you are ready to order is holding your money in your hand, so that it is visible to the person behind the bar. Once you have placed your order you will be given a table number that you place on your table.
