I second the recommendation for Pier 21 in Terminal 21. there are little stalls set up side by side in a grouping of about 50 in all. There is every asian food style imaginable. You load up a purchase card and walk around from stall to stall ordering what ever you like. Mix and match all you want. I ended up with a Japanese noodle soup, a chinese duck platter and some stir fried veggies plus a water for around 400B. Insanely cheap and great food.
