Food is great, the line-ups are TERRIBLE - I recommend you make reservations because they will for sure make you wait for more than 2 hours if it's that busy. It's also because they have the cheaper menu items before a certain time. The food selection however is good and for my first dim sum experience, it was great. I would definitely recommend it.
Food: 4/5, large selection and tasty dishes too. I've had one of the best lotus-leaf gluntonous rice and shiu mai from here.
Service: 3/5, food comes quickly but a lot of emotionless servers around who I'm sure are ok but look angry.
Ambiance: 3/5, very large area with many of the lazy susan style round tables which are great for large parties and conversations and sharing food.
Price: 3/5, It was around $20 per person for a LOT of different dishes.
