If you're ordering on the menu and not a buffet, one of the better options is Mongolian beef. If you're in luck, you'll get the good kind that's practically a dry spice rub and minimal peanut oil for cooking. If you're a little less lucky, you'll get the kind with a sauce that contains a little cornstarch. (I'm not on IP and am not sure how much that would throw you off.) You might want to ask if they can leave the starch out of your portion.
If you go with the buffet, is it one of the places where you pick your own raw stuff, then take the plate up to the chefs who cook it to order for you? If so, go wild--you can eat a TON of goodies cooked to order. If that isn't an option, gravitate toward grilled items and steamed veggies; I know most places here have a pretty nice grilled/boiled seafood selection, but that might vary. Chicken skewers/chicken satay makes a nice appetizer.
Although I'm not on IP, I feel safe in assuming rice is off your menu, but you knew that one already.
I hope you have a wonderful time and that whatever you choose to eat is delicious!
