In Bonn, they speak German. However, in the state of North Rhine Westfalia, a different dialect is spoken that isn't standard German. Most locals say it's just an accent, so it doesn't really have a name.
The type of money used here is called the euro. Back when Bonn used to be the capital of Germany, the type of money used was called the Deutschmark (doytsch-mahrk). In 1991, the capital moved from Bonn to Berlin, but Bonn is still considered a sort of unofficial second capital of Germany.
One liter of water costs about two euros, which is about $2.50. In Europe, drinking sparkling water is the norm. Tap water is still sold, but it's not as common to see people drinking it.
My friends and I got to eat delicious frozen yogurt in the city center. I got watermelon and strawberry flavored yogurt! I put a lot of toppings on it as well, like chocolate syrup and oreos. Sometimes it's nice to eat food that is the same as what I would have at home.
