Look, let me start by saying that, despite more good places popping up as of late, it can be really hard to find good Thai/Chinese/Eastern Asian type food, so it's all relative. So I am rating this place not on a grand scale of Asian food in Berlin, or even compared to the stuff I miss from the US, but relative to other Asian and specifically fast food places in Berlin.
As far as quick eats Asian places, this is about as good as you'll find. €4.50 will get you a box with lots of rice, veggies, and chicken (€1 more for duck) and your choice of decent sauces. After trying every other place around there this is the only place in this category that I have ever come back too, and now I come two or three times a week. Generally, avoid Alexanderplatz as all of the food around is garbage, but if you are there all of the time (I work one tram stop away, and food is worse by my office) and need a decent quick meal, this place is pretty solid. read more
