Open 11am to 11pm (all, apparently)
Can be independently owned, or owned by a brewery
Food is available (Poughman's Lunch, for example. Remember that one from BritishSpeak?)
[Typically it consists of bread, cheese, pickle (English coleslaw) and apple or lettuce or something in the way of a fruit or vegetable.]
Fish and Chips are also usually quite good at a pub.
Some interesting names (though not nearly as interesting as the Slap & Tickle):
The Bag O' Nails
The Friend at Hand
The Green Man
Clam on the Anchor
The Hoop & Grapes
The Catherine Wheel
The Rose and Crown
The Fox and Hounds
These are more interesting than the usual American bar names such as "Bar", "Open 9am" and "Drive Thru".
