If this review looks like a summary of all of the other Yelp reviews, it's because Yelpers have really tagged Voila, at least collectively. The bottom line is that Voila does a lot of things very well but just when you are going to say you love the restaurant, there is a discordant note or two. Or three.
I think our experience was typical. Two of our entrees were delicious -- the lamb chops and the scallops. Another, the branzino, was badly overcooked and dry. The desserts were great (floating island) but the asparagus salad was totally unremarkable and without flavor. The ambiance was comfortable and uncrowded, inside and out, but the server (not the owner) was humorless and seemed disinterested or perhaps just distracted. The wine list was thoughtful and reasonably priced, but the overall cost of about $70 per person was a shade high.
Perhaps this is meant to imitate a Parisien bistro, but it does not compare with even the average dinners we had in Paris (for less money).
Overall we still enjoyed ourselves, but the value is not there and the food has too many misses.
