In layout, urban pubs typically feature several inter-connected bar-rooms of different sizes and designations, usually clustered around a large central bar area with several serving outlets. Many suburban pubs also often include an outdoor or semi-enclosed area known as a "beer garden", where food and drink was served and where (especially in recent years) families with children are able to eat (although children of course cannot be served alcohol and they are not permitted in any other area of the pub).
