I had the lunch buffet with a student of mine from Beijing. If I had to sum up everything in one word, it would be 'meh'.
Everything we had was decent, but not really great. Between the two of us we had a little bit of everything and while there was nothing that I particularly enjoyed, there was nothing that I found disagreeable either. The service was good too the few times we needed anything.
Overall at around $7 for the buffet the price isn't bad - so if you like stereotypical heavily Americanized Chinese food and really want to stuff yourself with a meal that isn't bad but is so unremarkable you'll forget you ever ate it by the next day, this is your place.
