I personally think that their serving sizes for pho are larger than most other places. What may be a regular bowl at Saigon can be a large bowl at other Vietnamese places in the area. Plus, I'm a big fan of broth and it's pretty decent here. All this for not a lot of cash. It's just about the best bowl of pho you'll get in Chandler.
*Update*
Dropped it down a star because the last few times I've been there, the pho has been a bit sub-par (noodles were weird and they were stingy on the beef). You really should only eat here if you live in Chandler and don't wanna drive up to the better places in Mesa, Tempe, or Phoenix.
*Update 2.0*
They've really gone downhill, based on the last two times I've gone. I wouldn't even bother ordering pho here anymore. The rice dishes may be it's only saving grace.
