Restaurants customize services for frugal diners

(ECNS)-- Recently, many restaurants in China like this one have joined the campaign to reduce food waste.

Various measures have been taken to encourage diners to empty their plates.

Some offer small gifts to those who take away unfinished food.

Others have adapted their menus by offering dishes half their former servings.

"N-1 ordering" is also recommended, meaning the number of dishes ordered should be one less than the number of diners in a group.
