Kitchens, as the heart of a restaurant, have been kept secret from consumers. Since food safety issues have been topping the agenda many of the country's caterers are ready for tougher supervision. In southwest China's Chongqing Municipality, some restaurants now open their kitchens to the public.

Not sure what they are serving you?

You are more than welcome to see for yourselves, in the kitchen.

Liu Yaqin, Restaurant manager said "Customers first need to show their identities. Then they should wear the clothes that we provide. And we will accompany them through the whole tour."

The move comes after the central government initiated a crackdown on violations against food safety.

Citizens applaud such transparency, believing its positive influence will rebuild mutual trust.

"We don't know what they have or do in the kitchen. It's much more comforting if we can see for ourselves."

Right now almost 20 restaurants in the city have been opening their kitchen for public tours.

While restauranteurs are busy demonstrating their commitment, supermarkets have their own ways of securing the confidence of shoppers.

Special shelves are used in 13 supermarkets in Chongqing, to distinguish the food about to reach its sell-by date.

Chen Shouqing, Supermarket manager said "Here we put food when its shelf-life is almost due. These products are sold at a discount. Customers can make an informed choice."

Such policies have not existed before.

So it is seen as a big step forward.

But regulations are still ambiguous about what kind of food should go on this shelf and how long before its expiry date.

Last month, Shanghai departments concerned found moldy steamed bread treated with sweeteners and dye to make it seem fresh.

The case shocked the country. China has since called for tougher action on tainted food.
