How to get to Syster O Bror:
The easiest way to get to the restaurant is by subway Red line 14 to station Tekniska högskolan (note that line 13 and line 14 always leave from the same platform; make sure you are not entering line 13). Use exit Roslagsbanan/Tekniska högskolan, which is at the end of the train when coming from the centre of Stockholm, e.g. T-centralen. Walk along Drottning Kristinas väg about 200 m and you find the restaurant on the right.
There are also a number of buses that will take you to Östra station, a bus stop that is at the same place as the subway station Tekniska högskolan. You will find time tables and line maps at www.sl.se/en
