Eating-out is generally considered to be of increasing importance as a
form of food consumption even though there are differing definitions
of its scope. There have recently been some noteworthy additions to th
e available statistics on eating-out in the UK and these indicate its
growth through time and its pattern across society. Eating-out involve
s a degree of interaction with others and has been studied by sociolog
ists as well as by those whose interest primarily stems from ones in t
he agri-food chain or in food consumption. It also raises some interes
ting issues about how 'externalities' (and, in particular those arisin
g from smoking) are best allowed for in circumstances in which both ap
plication of the polluter-pays principle and very restrictive regulati
ons may be considered impractical and inappropriate.
