Went here a second time. There wasn't as long of a wait this time but still expect to wait for at least 30 minutes at busy times even with a reservation (make reservations!). Service is decent... very quick if a bit curt.
This is still my favourite dim sum restaurant. However, I now recognize that not all of their dishes are hits. I also discovered some amazing dishes I didn't try the first time. My ranking of everything I've tried here below:
Must-get: Baked BBQ pork bun, har gow, dragon boat fried rice, baked egg white milk tart
Excellent:: Steamed BBQ pork rice roll, siu mai, duck meat and seaweed rice roll, steamed sticky rice with chicken in lotus leaf
Decent: Steamed beef balls, angus beef rice roll, shrimp and veggie rice roll
Avoid: Any of their congees including the plain congee and the katsuobushi and peanut congee. Also, steamed shrimp dumpling in soup
