China Rose is one of the better buffets in Calgary without a doubt. It's an older restaurant that's been around for awhile and the staff are pretty good. The size of restaurant is is pretty big with a decent size of buffet table with plenty of options.
The food has always been good over the last few visits and I could confidently say it's consistently good. Freshly made buffet dishes and the ginger beef has been really good. One time it was off with dryness and taste but every other time it's been a solid awesome.
The location of China Rose is a bit shady if you haven't been to the North East Calgary before...but haven't had any issues with parking and it was worth the drive to go eat here.
The overall experience is great and I would definitely recommend trying this place out if you are looking for a good Calgary buffet to try.
