The best restaurants serving Hamburgers food in Newham London

I had really bad experience in the restaurant. We Order burgers along with the fries. The fries contain a long hair and they give us the fries when we asked them, their service is too slow. People come after us they all got the drinks we waited 30 min for the drinks and when they serve the drinks they make it messy and the bartender she is very rude while serving.
