Here is a list of professional labs in Germany, Switzerland and Austria.
Just scroll down and you find the labs in Munich on page 3:
As Germany is "film shooters paradise" you will not have any problems finding excellent labs.
And you are not dependent on labs in Munich. There are enough first-class mail-order labs, too.
For example Photo Studio 13 in Stuttgart. They are developing every day and send your films back the same day. So you normally have a turn-around time of only two days. The quality is excellent, and the price is low.
And of course you always have also the possibility to get films and processing at "every corner of the street": In all Rossmann, dm and Müller drugstores. Prices are extremely low.
