Let's be real for a second. This place is open everyday, from 11 am to 6 am and always has at least 30+ dishes. It is not going to be fresh and microwaving will be a reality of the operation. Because the food sits for a long time, the oil will float to the top this does not mean the dish has more oil than usual, you just don't see it in other places.
The food itself is ok. It is not great, but not terrible either. And they don't try and charge you more than it's worth either. There's a reason you see cabbies eating here, the food offers a god a value and tastes good enough.
Also, I wouldn't recommend eating there. Get take out, eat it at home.
