The best restaurants serving Chinese food in Hampstead Town Camden London

I used to regularly go to Goldfish in Hampstead before it moved to Chalk Farm. Before moving it was run down space but good quality tasty food and decent service. Today we tried the new Goldfish now in Chalk Farm and the food and service was awful. Firstly, the place was freezing and we including others were sitting inside with our puffer jackets which the staff did not seem to care about. our food was brought luke-warm, not at all to its usual standard and at completely different awkward times. We had to ask for tap water many times and the servers were completely un-attentive even though there were about 8 of us total in the whole restaurant. I don't often take time to leave negative reviews but I don't recommend visiting Goldfish if this is their new standard.
