A best-selling author of spy novels (which I also devour) left, I believe, clues about the identity of Et Voila: "a popular Belgian bistro located on MacArthur Boulevard in Northwest Washington..." with a "narrow dining room" - and so it did not take much sleuthing...on my part to discover Et Voila. Being of Belgian descent, and proud of the quality of Belgian cuisine, I just had to try it. Et Voila is very popular and for all the right reasons: the kitchen is wonderful, the service attentive, and it clearly has the support of a devoted clientele. My dinner partner and I both ordered steaks, which are fairly generic items but they were wonderfully prepared and served with salad and frites. For appetizers, we both had mussels (mine steamed, his baked), which were terrific. The pastry chef is fabulous so for desert we ordered the profiteroles and those - served with a super creamy ice cream - were out of this world. As described, the dining room is in fact very narrow and the seating configuration is limited - so does not have anything to add to the dining experience in terms of atmosphere or privacy - BUT somehow the whole set up contributes to the feeling - shared by everyone dining there - that you have found something pretty special with Et Voila. I can't wait to go back!More
