Arrived at 1pm for a Monday din sum lunch. The room was full, and we were told there was a 10-15 min wait. We were seated before the 10 min was up, and were welcomed into a lovely dining room. Staff were friendly and efficient. We ordered the standard charcoal bun, shrimp shumai, chicken feet, sticky rice with duck egg, stick rice with roast pork, and some pickles. All was delicious. The sticky rice with duck egg was particularly memorable. As several people have noted, the charcoal bun is very photogenic. The bun itself has an mildly unusual charcoal flavour, which I found tasty. The filling is delicious.
Fun spot. Will come back for a proper meal.
