Åpent Bakeri, Parkveien 27, Oslo.
Coffee, cakes, home made bread, brioches, ... in Norway it's all about enjoying life while treating yourself a good sweet piece of cake, pie, or whatever it is you like. You can find a coffee shop on every corner of the street and - I assure you - it is always busy.
My personal favourite amongst the variety of cosy little places stocked with beautiful designs and sweet delights is the so called Åpent Bakeri. It's all very clean and simple: well baked bread, friendly staff, good prices and the best brunch in town (see the last picture):-).
So, when you're in Oslo and you'd like a simple well-priced lunch, Åpent Bakeri is the place to be (although I must say that I'm far from having visited all the coffee-places this capital has to offer).
