Don't know what the complaints are about, but I'll offer this....
Disclaimer 1: I didn't have the Pho.
I did have the shrimp with vermicelli noodles which was absolutely delightful. The shrimp were perfectly grilled and seasoned and the bowl came with ample veggies and fish sauce which was not overly fishy. The spring rolls (sans pork) were also wonderful.
I'll be back with an update.
Disclaimer 2: I'm not from CA nor am I Vietnamese.
Disclaimer 3: Once, I did eat solely Vietnamese food for 7 days in CA.
