It's been so long since I've lived there I can't recommend much. I will say if you find yourself closer to South Central Denver, Kokoro Bowl at Colorado & Evans is fanfuggintastic Japanese fast food diner type food.
Lived in Denver for 30 years, and cook professionally. Suggest you consider going to Vancouver instead. That, is a town that has great Chinese food! Our Chinese food is not terrific, but we do have great Vietnamese food if you want to try a change of pace. Suggest New Saigon on Federal. If you must have Chinese try Imperial on Broadway, it is better than most.
Not sure if the reply is too late, but as mentioned the area around Alameda and Federal has the highest concentration of authentic Chinese restaurants. JJ's on Alameda is good as are Kingsland and SuperStar Chinese Restaurant in the Alameda Square strip mall. Please feel free to PM for questions.
