Having just eaten at Everest, I was reminded again of what a civilized experience it is. I love Blackbird, but, as Vital Info pointed out, it is very noisy, and service is always not top-notch. Everest is comfortable and the service is flawless. The food is perhaps less adventurous than at Blackbird, but superb. There are several different tasting menus to choose from, too. We had a risotto with snails, a marbe of pheasant, quail and one other bird, and I had the venison for an entree - my husbamd had a lobster dish. It was not what I would call cutting edge, but it was wonderfully delicious and well-executed.
Or, as someone else suggested, think of Avenues - again, several different degustations available, fabulous food, in an elegant room with wonderful service.
