On a clear day in June the terrace has sun 10:50–20:40, about 10 hours in total. In short: sun at lunch and afternoon sun. The sun lasts well into the evening, but going by the opening hours the place is closed by then.
The story of Mr Cake
MR Cake was founded by the pastry chefs Roy Fares and Mattias Ljungberg. The first café opened in September 2017 at Rådmansgatan 12, in the former School of Architecture building now known as A House.
Roy Fares was born in Lebanon in 1984 and grew up in Örebro. He won Sweden's Pastry Chef of the Year in 2010 and became known on television, including as a judge on Kanal 5's Dessertmästarna. After Stockholm, MR Cake opened at Stenpiren in Gothenburg in spring 2019 and has since grown into a small chain.

How Stoligt works it out
Every ten minutes we draw a line from each terrace toward the sun and check whether a building or hill is tall enough to block it. Building heights come from OpenStreetMap and ground heights from Lantmäteriet, the Swedish mapping agency. The times assume a clear day, so clouds are not included here. They are on the live map, which shows today's weather.
Trees, parasols and awnings are not in the model, and we don't know exactly where on the pavement the tables stand. Treat the times as an educated guess, often accurate to within ten minutes.
