If you're very hungry and are traveling on a budget around East London ... then Noodle King is for you :)
Chinese and Oriental cuisine with fresh ingredients. Admitedly not the best food but still, for 3 or 4 pounds, it's more than you will probably be able to finish. When looking for fast food I much rather visit Noodle King than various fried chikens or Mc-Burguer-stuff.
