I can not understand how one can give this disgust...

I can not understand how one can give this disgusting restaurant more than one star .... no, yes, no stars.
Disgusting food, unfriendly, slow and unmotivated service.
Language skills of the service hardly available, neither German nor English ... and sorry Indian we could not.
Never again!!!!!
Is also offered on Groupon, nor is the service even worse, if you wave the note.
