Good alternative to Mandarin, but not my first choice. Food quality is okay, but selection isn't the greatest. They do have the option to make your own stir fry which is great. Their hot dishes are good, not great.
One really great perk to be honest - their drink options! Self serve, and its great.
I'd say yes - it's worth the value. I'd definitely prefer/recommend going to the Mandarin but again - it's a great alternative and a tad cheaper than the Mandarin.
FYI - don't go right at the start of dinner!!! I had to wait over 10 minutes in a line just to reach get to one of the hot counters - it was madness.
