I went to Bleu Ginger in Milpitas: it's on South Abel Street, in the same plaza as Swagat:
I had the Bo Luc Lac, which is purported to be a facsimile of shaking beef. It was not quite pungent enough, and not as good as the shaking beef at Xanh in Mountain View.
I also had the Bleu Ginger rolls, which have shredded duck. The rolls are rather thin - more like taquitos. They have a very generic, processed flavor - not recommended.
Finally, the ca phe sua da consists of very weak coffee, with a very small amount of sweetened condensed milk. Why is this situation always the case at high-end Vietnamese restaurants?
Several days later, I went there for lunch. I was seated and got the menu, but then the waitress disappeared for about 15 minutes. So I left.
