In most of the cities there are plenty immigrant communities that actually diffuse their culture and traditions to the country they are staying in. To take an exaple, I went to such community; it was Turkish mostly and I've made an expedition myself to show you the example of how immigrants can impact other culture by spreading their traditions.

This is how a typical Turkish neighbourhood look like in Salzburg. Usually, it is either low or middle class. It is located just near the train station and has a lot of Turkish stores, restourants, and other buisnesses around. I saw a lot of Turkish people in this community and they are living there, so we can assume that this is a Turkish community. 

Just on the way to the neighbourhood shown above, I saw a lot of  such stores and cafes that have traditional routes from Turkey. This small cafe, as they call it "bistro" has typical traditional fast food of Turkey, such as "kebab", "durum", etc. and mostly, Turkish people from those communities are visiting it and all the cashiers and cooks are speaing Turkish. I visited it and had one of those traditional meals, inside, the traditional music was playing as well as Turkish channels on TV. 

Another traditional store was selling fast food. National products and food that are common to eat on their motherland. Those products were mostly snacks, such as nuts and sweets, such as "rahat lukum". There were a lot of kinds of their national food that not only offers fast food. 

Down the street, I saw the store that was selling national cloth and what is important, mostly for women. As the way how women are dressed in Turkey is one of the biggest traditions they follow, this tradition is even connected to religion. The store is selling special scarfs that women have to wear on their head and hijabs, that by traditions, they have to wear it casually. So most women from the community are going to this store, as it is the closest one to the neighbourhood, and buynig their traditional, even cultural cloth.

This is the view on the fast food "bistro" and this is the best example of how the traditions of immigrants impact city life and businesses.
