BB1 Vietnamese Bistro, Hysan Place, Causeway Bay HK

 Finally found this restaurant in Hysan Place, but am disappointed with both the food and services.  The food isn't impressive though not too bad.  The beef broth isn't as nice as the other Vietnamese restaurants I tried, and it's quite salty. The chopped scallion is also very salty.  The common mistake is that all these aromatic ingredients were prepared for a long time that it lost much of the original aroma.  Service-wise, the waiters and waitresses often kept their heads down without caring for service.  Took a long time for checking the bill.  Couldn't help it and brought up these to the waiter who responded.
