I recently bought a voucher to take my family here for a Sunday Yum Cha, not knowing what to expect. Well let me tell you it was fantastic.
The place is not in the heart of Melbourne's China Town, but worth the extra few steps to get there. It was simply palatial, with gold and marble everywhere! The place was very busy and we were shown to our table very efficiently and the excellent service did not stop there, along with wave after wave of an excellent variety of Chinese delicacies for us to chose from. The Chinese beer (Hamlin?) included in or meal deal was also excellent.
Voucher or not, we will definitely be back and highly recommend it for a great Sunday (or any other day) lunch experience, but I suggest you book first!
