The noodles yes are quite good but nothing exceptional. Better places nearby.
Cheap? Not anymore than many other places in Chinatown.
Why I wouldn't recommend eating here? The service. Rude even by cheap&cheerful standards. And slow. Very very slow. I had to wait half an hour for a bowl of noodle soup. And this is where the rude comes forth: twice I asked about my meal and both times got don't-give-a-XXXX replies.
So fast it ain't (unless you order from the gloopy hot counter).
