That about describes the general idea. It also includes - if you want a chat and drink without interrupting other peoples enjoyment... a generally informal attitude, some singing, some music, enough space to spread and for both to happen in different parts of the pub. Perhaps a bit of silliness to occupy the quieter parts of the day.
Bring a tent, camper or caravan, but tell us if you are doing so. It allows the landlady and landlord to cater for enough beer, food etc.
Quack!
