I know food. Everything about this place was first rate. The room was engaging, although we sat in the back room which appeared quieter and a bit more formal than the front section. I would request the back again as my wife and I went after a long day of walking and enjoyed the softer environment of the back room.
The wait staff was attentive but not intrusive, knowledgeable but not pompous, and had an appropriate sense of humor without auditioning for SNL.
Service was perfect, the timing of the dishes, which we had many of, was spaced evenly without a rush or a wait.
The food, absolutely brilliant from start to finish. All of it was complicated in its simplicity and what I liked about it was we were served without a lengthy discourse on where each grain of salt came from or the genealogy of the tomatoes or how brilliant they were to think this dish up. They simply served it and let the food do the talking. And it all spoke loudly with confidence.
I would go back every week if I lived in DC. It is expensive but, if innovative, good and honest food is your thing....It's worth it.
