Excerpt 1 uses an informal language and tone, while excerpt 2 uses a rather formal, structured language and tone, which make it more formal than excerpt 1.
This difference could be explained by analyzing the target audience of each text: excerpt 1 is probably aimed at promoting the new coffe shop and making friendly references about the young people who attend there. Excerpt 2, on the other hand, makes emphasis on the business or economic element of the new shop, so it is probably targeted to businessmen or people who are interested in that aspect of the new business.
