I'm going to stick to 3.5 stars for now. We had the pork and cabbage potstickers and the vegetable dumplings (with mushrooms, greens and glass noodles). The pork potstickers were definitely the highlight. Seared with just the right amount of crunch on the bottom with a nice soupiness inside. They definitely know their potstickers' worth too - for the same price as the set of 12 veggie dumplings, you only get 5 potstickers.
Nothing much to say about the veggie dumplings - they were only mediocre :( This was what made it 3.5 stars rather than 4.
I'd definitely go back for their pork potstickers though and try the lamb that everyone seems to be raving about.
