The best restaurants serving Hamburgers food in Millwall Tower Hamlets London

I went here with my girlfriend after the weekend light show and what a disappointment. I know that they were busy but they really should have anticipated a rise in numbers. Lots of food options were not available (sweet potato fries, onion rings, etc) and that which we did have took a long while to queue up for. Ordered a large beer but was delivered a small bottle. The staff corrected this, otherwise it would be a 1 star reveiew. I will not visit this branch again, as had told my partner that the chain was good. The worst branch that I have ever eaten at.
