Do they have Mountain Dew in Germany?!
Answers:
Pepsi cola is available in all of europe, mountain dew however is not so popular. I lived in Munich Germany and only one supermarket I know of sold it: "Hit"
I also noticed that mountain dew was available at many gas stations, don't ask me why, but it was too much of a hassle to go out and buy it.
The same goes for Dr. Pepper, although I think it is increasing in popularity.
I could imagine that it's easier to find Mountain Dew and Dr. Pepper in Berlin because there is quite a large American community there and it is also a more international city, however I can't really say.
In England however Mountain Dew is quite easy to find, Dr. Pepper is very big in the UK and all supermarkets have it.
I don't know about France though, but in I imagine it will be similar to Germany...
