Having dined last year at Bistro Aix and feeling it was loud and for the later 20-30 somethings, we thought we'd try Rest. Orsay. Definitely make reservations. We arrived at 6:30 and no line. By the time we left the line was out the door. The restaurant is loud but not loud enough that you can't hear the music. We were greated by "hey" which needs to be addressed but it went up from there. Our waiter Brian, was wonderful. In fact, we enjoyed talking with him so much it would have been fun to have him join us!! (Thursday night line up..). He was professional, knowledgable, attentive yet not overly so. The food was delicious (although the frites are better at Taverna) and we splurged and had dessert. All in all, a wonderful meal, fantastic waiter, a bit expensive (we are from the DC area) but a nice, enjoyable meal.
