Don't know if you can get in at Komi or Restaurant Eve, but if you can, do.
Vermilion is lovely. So is walking around Old Town afterward if you do that or Eve.
Or you could go to the steakhouse at the W, walk around the White House/Lafayette afterward, then drinks and dessert at the W rooftop bar.
I've heard Quill at the Jefferson is very nice, but haven't been.
