Diamond House Chinese Restaurant is awesome. I actually crave their food. My favorites are their Sesame Seed Chicken & their Cream Cheese Won Tons. I could get my weight in their won tons. They are clean, friendly, & the price is right, especially if you go during lunchtime. You won't leave hungry for they have all you can eat buffet. They also have a Japanese side to the restaurant which I have yet to try.
My whole family loves the Diamond House. My husband and I discovered it while attending college at Tusculum years ago. We stayed in Greeneville and are so happy the Diamond House is still around. The food is the best Chinese buffet I've ever had. When we ever try others, they never measure up to Diamond House. My 5 year old could eat a gallon of their wonton soup. My favorite is the House Special, just kind of everything together, love it! I can't get enough of their cream cheese wontons. Mmmmm! Whenever family visits from out of town, everyone votes for Diamond House for a big dinner out with the whole family together. They've even given us our own room when we had a lot of people all at once. I still haven't tried the Japanese part of it. I like the buffet too much!
