Joe and the Juice is a nice place to have a drink. Originated from Denmark, you can find Joe and the Juice cafes in many countries including US, UK, ... In Oslo, there are now several of them: one near the Stortinget station, one next to the"Steen & Strøm" shopping mall in Nedre Slottsgate.
What is the concept of this place? Mainly juices from freshly squeezed fruits and original sandwiches. A particular effort has been given to the name of the drinks (Prince of Green, Hangover Heaven, ...) and the sandwiches, though simple, are pretty good.
2 Drinks from Joe and the Juice
Sandwiches are thin so it is hard to do them justice in a photo
About the price: I am not sure whether the prices are the same everywhere but at Steen & Strøm, the juice costs 55 or 65 (small or big) and the sandwich is at 75. Not too bad for the area.
To conclude, if you don't know Joe and the Juice and are visiting Oslo, consider having a drink there!
