As long as there's demand, overseas fast-food chains plan to roll out even more Chinese-style menu items.

Here is the manager of a KFC chain store.

"We often come out with new products, pretty much once a month. They sell well."

However, some customers complained about the high price of the new products. For example, each Shaobing costs 10 yuan, or almost 1. 5 US dollars. That's five times more expensive than local products.

Here is Ms. Xu again.

"Of course it tastes good. But it's not cheap. I have a coupon here. If I didn't, I wouldn't be eating this."

One the other hand, KFC's biggest rival McDonald's maintains an essentially uniform menu everywhere in the world, while giving a discount to the price.

Experts say the Chinese market is huge and it welcomes new attempts. But it never changes the nature of the western kind of food.

Duan Fugen is the secretary general of Shanghai Restaurants Association.

"I believe that adding some variety won't change the main items offered on the menu. There are risks involved. It's not a certainty that the new item suited to China's taste will be popular. Only time can tell which business strategy will succeed."

Duan Fugen says Chinese restaurant chains are also learning from foreign fast-food groups. They are improving service quality and management method to face the fierce competition.
