4 of us had b-day dinner here, we ordered
1. Beijing Duck (HK$280)
Only 2 dishes of skins for 1 whole duck, seem they didn't cut all the skin of the duck for us (e.g. they didn't cut the skin from the drumsticks).
The skins were very fatty & oily. The duck quality was not good (maybe we are not 熟客ba). Not crispy as well. The pancakes were not warm and they were very thick as well. Not good.
北京樓 is much better.

2. 京燒羊肉
Quite tastful, no "So" taste, it's good.

3. 砂鍋津白
It's similar to 砂鍋雲吞雞 (but have some pork instead of 雲吞雞), it's got some 粉絲 as well, the soup was tastful, got around 8 cups of soup. Nice!

4. 拔絲香蕉
It's good as well.

The restaurant was quite noisy (waiters are throwing dishes into the place for dish-washing), so not good if you want to spend some relaxing time
In the end, we think the signature dish - Beijing Duck is not very good. Don't know why it's number one here in openrice for Beijing food. Don't think we would go there again...
