Burgers Berlin

What do you think of this place? Love it or not?
Decent fast food burger in Schöneberg
Just a gay mince south of the Nollendorfplatz is this third outlet of mini cross-city chain Burgers Berlin, which started in 2008 in Friedrichshain (Sonntagstrasse 2, S-Bahn: Ostkreuz) and landed in leafy Schöneberg in 2013. There's a bio thing going in the meat — you can opt for a bio burger or a non-bio version — and the fries are OK, especially as the prices are über-friendly. But the atmosphere's a bit off, including the service, and given that quality burgers are all the rage, this should be a lot better.
