If the Jamie Oliver restaurant in Westfield, Stratford is anything to go by I’m not surprised. Had a terrible meal there with appalling service and so did both my wife and daughter on separate occasions. Daughter is a Vegan (mainly for health reasons) and her non vegan pizza turned out not to be and she was ill afterwards. That shut a while ago. On all three occasions we were invited to return for a complimentary meal but none of us took them up on it.
