I am from Mumbai, and I have heard a lot about German bakery. Mainly because it is so popular and also because the bomb blast that took place near German Bakery few years back!
So there are two oulets of German Bakery in Pune; one is in Koregaon Park and the other is on Law College Road.
This outlet is a bar as well so you will see more of students hanging around at this place.
The ambience is great but the service is a little slow, so make sure you order your food well in time.
The food quality is excellent especially fish and chips and the pizzas. Even the cheesy jalepano nuggets were great.
Bit on the pricey side but if you are with friends then its worth it.
