I went to the place a few days ago with a friend of mine. It's an alright place to go for authentic dumplings.
The wait was not long at all, the restaurant is longer than it looks from the outside. I enjoy the fact that you can see the chefs making the food.
The dumplings were so-so to me, I wasn't wow'd by the flavour. Perhaps I'm not so well versed in eating dumplings. The presentation was not special at all. I did enjoy the atmosphere, the waiting staff was very nice.
I'd come back here again, if I ever get that dumpling itch.
