Hello, and happy new year! My mom is in town so I would like to treat her to a post-holiday dinner at a nice, somewhat upscale Vietnamese restaurant, preferably in Little Saigon/Garden Grove/Westminster area. I have already tried Quan Hy, and was suitably impressed. Just wondered if there were any other upscale places worth visiting in the Little Saigon neighborhood? Places specializing in seafood dishes are especially appreciated.
