The lunch special is cheap ($8-9), generously portioned, and comes out VERY fast (I was in and out in 35 minutes). If you haven't forgotten your high-school algebra, you can easily solve the restaurant equation for the remaining variable--quality.
The salad was just a tiny bowl of dressed lettuce with a few wisps of carrot. The "spring roll" was fried (I expected fresh) and had no flavor to speak of. The tom yum soup was okay. The pad thai was...odd. It was orange and glistened with a sort of gelatinous sheen. There was one lonely piece of green onion and a few sprouts, but otherwise no vegetables (thankfully it DID have peanuts). It actually tasted all right, but very different from any pad thai I've ever had. The chicken had been grilled rather than stir-fried and lent a nice grilly flavor to the dish. Also, there was tofu in addition to the meat.
But--it WAS fast and cheap. And the special runs from 11:30 to 5. Also, the service was pleasant and the setting lovely. I wolfed it all down because I hadn't eaten all day, but I probably wouldn't return.
