Thanks, sundevilpeg for your response.
We did go for dinner this past Wednesday evening. As you stated, the room is lovely and the service was excellent. However, we found the food pretty average. Maybe we ordered wrong. My MIL loves rice paper rolls so as appetizers we got a few varieties to share along with the shrimp paste/sugar cane skewers. The latter used to come with roll-your-own rice papers, rice noodles and tons of fresh herbs. These came simply with some lettuce and a couple of veggies. I thought the rolls were a tad dried out. The plum sauce helped.
My entree was perhaps a bad choice on my part but I am a pescatarian who was not in the mood for seafood so I tried their tofu sa te. It was dry, not particularly flavorful, and consisted mostly of sliced onions and green bell pepper. Others enjoyed their entrees more than me, but nothing was really deemed particularly interesting or special.
In the end, I felt like if they REALLY wanted French Viet cuisine we should have just shelled out the cash for Le Colonial where we've never been disappointed. Or just BYOB'd at any number of quality Thai joints.
They do have a nice wine list and I could see how it would be enjoyable, especially in warm weather, to relax with a drink in that space.
