Does Tourism Add Value Or De-value A Heritage Spot Or Icon?

Does Tourism Add Value Or De-value A Heritage Spot Or Icon? Personally, I think it's both. I'm sure all of us know that tourism can help to increase a country's economy and reputation. Tourists often visit a heritage site of a country, and as well as the tourists' attractions, which are usually the popular places or representative of the country. At the heritage site, tourists will get to learn about that country's culture, history, and the icon of the country. The Icon of a country helps to increase its reputation as it attracts tourists all around the world to visit the country to learn more about the country and add more value to the icon. 

However, to satisfy the tourists' needs, especially food, there will be western restaurants and eateries either near or in the heritage sites as people living in this century love to eat western food. One example will be MacDonald's, which I believe it exists in many countries. Let's take The Forbidden City of China as an example, isn't it weird to find a Western restaurant instead of a Chinese restaurant at the heritage site, where people are supposed to learn about China's culture and not the Western's? If so, what is the point of visiting China? Would you eat pizza or chicken rice in Italy?

One way the government can solve this issue is that they can try combining both Western and Chinese cuisines. This way, not only the tourists can have a meal that satisfies them, they can also try out and have an experience of eating Chinese cuisine, to know what kind of food the Chinese eat, to know China's culture better.
