I wholeheartedly second the recommendations for Edulis, Dandylion, and Chantecler (the latter is a former employer of mine), and all of the wine bars mentioned above.
I buy wine for Bar Isabel, mentioned above, and we'd be very happy have you in - I've never posted, but I've gathered lots of interesting info from your posts here over the years, so I feel like I owe you one!
You already have more than enough recommendations for your brief stay in our fair frosty city, but I would also strongly recommend both Brothers and Grey Gardens, for disorderly wine and food. There are also some really top-notch Chinese regional restaurants in the 'burbs north of the city if you'll be driving.
Note that wine prices here may seem a little shocking to Americans, as wholesale pricing isn't available to restaurants as it is in most of the U S of A, but you can take solace in the favourable exchange rate for now.
Feel free to reach out via PM if you want any more specific or less diplomatic advice, or if you plan to join us late at Bar Isabel.
