Single Fine Dining
i've found this to be a rather reiterated question as of late.. probably due to an odd influx of business hounds coming into town on their own. here are a few links found through the search function.
some of them are not bar specific nor fine dining, but the majority are.
of them, i'd probably suggest starfish and jkwb. however, i also haven't been to all the places listed in the links.
