Yee mee, the crispy kering version, is a deep fried noodle nest with a thick, starchy egg gravy ladled over the top, plus pork, prawns, fish cake and veg. The catch is the noodle nest is deep fried, so it soaks up oil before the gravy even touches it. That makes the crispy version one of the heavier noodle plates at around 620 calories with 28g of fat.
The soup version, where the noodles soften in broth instead of being eaten crispy, is much lighter at around 450 because it skips most of that absorbed oil. The protein is decent either way thanks to the toppings, but if you want lighter, go soup not crispy.
