They do not use fresh ingredients, or at least they cook so badly to make it seem that way.
People must have to convince themselves that this place is good because it's the trendy thing to do. But you're better off going elsewhere if you want good Chinese food.
Here's a general tip for you guys: if the place isn't predominantly Asian, leave. That's a definite sign that the quality is sub-par. But if you're white and have never had genuine southern Chinese food, you'll probably just barely choke down your "food" and agree with most people that this place is decent.
