I've been coming here for six years. I usually get the pho or the fried rice combination plate. My wife and I went this past weekend and we ordered the usual. As my wife was eating her pho, she noticed a worm on her spoon. It was very unappetizing and we immediately stopped eating. To give Saigon the benefit of the doubt, they do provide fresh herbs, so I understand this happens, but it was still gross to see.
I would still strongly recommend this place, just double check your spoon to ensure you are not eating tiny critters!
