I've had dinner here a couple of times, and I would recommend this restaurant if you're looking for a cheap and yummy meal. The prices are very competitive (we spend around $20 each) and the food is a great value for money. The place is very busy and you might need to wait a while, but the service is fast.
The only negative thing I've seen is that the staff are pretty rude, you won't see a smile or a charming attitude in them. Also they try to serve you very fast and as soon as you're finished they "invite" you to leave bringing you the bill.
The plates I recommend are the Pad Thai and the dessert that comes with a green sauce (can't remember the name)
