This restaurant had great reviews on TA, so we decided to give it a try. We arrived there pretty late, 10:30 pm, which is just half an hour before closing time, but the amazingly friendly manager let us in. She was so welcoming and so courteous, something you can't find in some European countries all the time. The restaurant is very clean and nicely decorated.
The food was AMAZING! Especially the massaman curry. The presentation was beautiful and the prices were very reasonable. If I lived in Berlin, I'd go there again and again.
Go there on a day when you're planning to visit checkpoint Charlie, it's only a few minutes away.
