Pho Sing Sing is a family owned and run restaurant. You can tell they take pride in serving high quality authentic Vietnamese food here.
Be aware that the Pho does have msg, like almost all Pho places. There was a yelp tip that said no msg here, I asked our waiter about it. He said he didn't know, so I asked one of the cooks who said they do use msg, but not a lot.
I tried the spring rolls and several vermicelli bowls. Everything was delicious. The vermicelli noodles were perfectly cooked, the bean sprouts and other veg was fresh and crispy, the meat was nicely trimmed and marinated, and the fish sauce was perfectly balanced.
So far this has been the best Vietnamese I have had in Chinatown, it sets a much higher standard for how good this food can be. I will definitely be coming back to try the other dishes.
