I love this place and have been several time!
The concept of having a healthy meal prepared in front of you is very appealing!
The option for having Chinese food buffet is a great secondary option when the lines get busy for the Mongolian style meal.
The only downside (as far as I recall) is I believe the meal is more expensive if you go in the evening or on the weekend. This concept has always seemed silly to me.
Definitely recommended for a good meal!
