There's three Chinese restaurants at one general intersection area here in Independence.
The Hong Kong Tea House - An actual restaurant, good food.
China Buffet - Buffet, which isn't too bad either.
Gold Lion - Actual restaurant, I've only been there once. I don't know if having a TV playing on one of the tables does anything to help or hurt a restaurant.
All of those are around the MO-78 and MO-291 area. If you enter the area on 78, you'd have to turn right into the parking lot (there's a huge Price Chopper next to the restaurant). HKTH is on Hub, which is off of Gudgell (which is south of MO-78). Gold Lion is in the strip east of 291 and south of 78.
As for the other restaurants.
I've never had Panda Express (in the Independence Center) although i've had Teriyaki from the Japanese place in the Center.
Wing Lee's (off of US-24, on Atherton) is a small buffet. And they had "Chinese-style donuts" (which was sorta like a donut without a hole and with sugar on it)
Cathay Express (US-24, east of Lee's Summit Road, before Salisbury) is a little place that appears to be similiar to a drive in. But I haven't been there.
Peking Express (US-24, east of Sterling, Northside of the highway) is pretty much Chinese fast food, with a drive-thru and all.
China One (formerly Apple Chinese, US-24, east of the High School, in the old Waid's building) wasn't too bad either. It's buffet-style.
Shanghai Boy (Noland Road, south of 23rd) hasn't been open either time i've went by. They have a drive-thru and a mix of Chinese meals and American fast food. Yes, Cheeseburgers and Chinese. Here's an article on their Lee's Summit location: http://www.thex.info/stories/0904/0904009.shtml
There's a few more here that I haven't been to. For a town of 110K, I don't know how many Chinese restaurants are to be expected.
