3.5 stars.
One of the better dim sum places I have been in RH. I see a few bad reviews on this place, and have never experienced stale or cold food yet, but to be fair, I have only been here a handful of times.
All the food we received came out piping hot and fresh. Their siu mai is one of the better I've had and the curry chicken pastry was also a hit.
The only meh thing was the ham sui gok. One of my favourite dim sum dishes and it tasted super weird.
As per some other reviews, they service is pretty crappy, but it's what you expect for an insanely busy chinese restaurant. The server threw all the plates down at us and barely spoke or made eye contact. Hard to get someone's attention and it took longer than it should have for them to notice we didn't have a menu.
Came at 10:30am on a Saturday. The wait for our table of two was just over an hour. Annoying but also expected.
