New Sky is one of those places that for me, I would only go out of slight desperation (ie 3am and it's one of the 3-4 places that it actually open)
The place is always understaffed and you will have to flag people like crazy to get anything (water, tea, etc). It's pure agony.
The food is just OK - you could do worse in Chinatown - okay - a lot worse. The menu has all your typical Cantonese dishes. Portions are huge and greasy, but that's pretty standard for the area.
Their Moo Shu Pork is my regular order, but the seafood hot pot is a decent pick too.
It's not incredibly cheap either, for Chinatown, but if you're hungry at 3am it's a decent bet. If you are dining during normal hours, go elsewhere.
