Avoid fried foods and heavy sauces and oily looking dishes eg - beef on black bean sauce etc ..also avoid noodle dishes
You could also order steamed dumplings maybe with vegetables/ mushrooms etc
One cup of steamed rice is good .. it'll fill you up! Avoid fried rice
Watch your portion sizes too lots of Chinese restaurants serve big sizes meant for sharing
Chinese food is yum and very easy to go overboard you don't want to leave with that oily heavy feeling
Have fun .. Their fortune cookies are yummy
I think you should sample a bit of everything but don't overindulge. Just eat until you're about 80-90% full and then stop!
But yes, get the steamed white rice and try to eat a bite with every single dish (that's how chinese people usually do it lol), you fill up faster.
The soups (egg drop, sweet and sour, etc) are very low cal so fill up on those before the meal, steamed fish or pan-fried fish with vegetables, tofu-based dishes (minus mapo tofu, which isn't too awful in small quantities but they do use a ton of oil), vegetables like bean sprouts, bok choy, chinese cabbage, eggplant, aren't too bad either!
You can also ask them to go lighter on the oil :)
