Pretty similar quality to what you'd get in Berlin (imo), although at a higher price.
Ordered the lamb/ veal doner teller (on fries). I really liked the combo of flavors. The meat and fries were both tasty. Thought it was fairly good value too, as the portion size is quite filling. I would've preferred to pay a little more to get more meat... need to check if thats an option next time.
Also tried my wife's doner sandwich, which was tasty as well.
They sell the matte drink thats pretty popular in the clubs in Berlin.
I'll definitely return.
