I came to Diamond China with some friends on a late night after watching a movie (see below yelp review too for my movie theatre review :) It's one of the Chinese restaurants that is open late in Vegas outside of the Strip. They are open till 2:00am Friday-Saturday and Sunday-Thursday 11:00-12:00am.
We ordered to-go and I was quite surprised how quickly they got our order cooked and ready. The food we got were #150-deep fried pork chops with pepper salt for $7.75 and the #130 boneless chicken with vegetables for $7.50
The boneless chicken with vegetables was nice because there were different kind of veggies. I found the deep fried pork chops a bit on the salty side. Overall I thought the food was just average. Portions were small which was a bit disappointing. The sizes were not what I would think would be served for a dinner. It was small and not something I would expect for family style Chinese.
I like that this is open late & I like their quick service but other than that I found this place just so-so.
