If you like Whisky, Corona's downtown has a great selection. It's a cigar bar, so if she doesn't like the smoke, then I would avoid it, but the do have a great selection. As does Ceviche. It's a tapas bar downtown on Church St.
Kinda hard to find a great bar with a decent selection of dark drinks. Most have the usual bar staples and that's about it. The two I listed above have a nice selection though.
