According to Wikipedia: "Fern bar" was an American slang term for an upscale or preppy (or yuppie) bar or tavern catering to singles, usually decorated with ferns or other greenery, as well as such decor as fake Tiffany lamps. We wouldn't say this spot is preppy, but they definitely have ferns inside and out. And it's on this list so clearly it's a good spot for your single self to bring a date.
