We order from here on a regular basis. There are not many places that will deliver to W. Champaign, but that has never been an issue for Rainbow Garden. I first started ordering delivery from them 13 years ago when I first moved to town and lived in a different location. Sometimes we have the same delivery guy I had back then, and he remembers us too.
My wife's favorite appetizer is the Pot Stickers, but the other appetizers are pretty standard fare. We always order the General's Chicken and Barbecued Pork Fried Rice. I have recently been ordering the Singapore Style Rice Noodles, and they have been very good. We've tried many of their dishes and all of them have been pretty good. I'm a big fan of their hot-&-sour soup, over other similar places in the area.
Delivery is always very quick. I've also eaten in the restaurant for lunch a few times over the years, and that is also a pleasant experience. This is our "go-to" place for Chinese delivery (partially for lack of many other options).
