Looks like my holiday nightlife wish was at least semi-granted: A dance company has started throwing weekly parties in the old Gardel's space (29 S. Front St.).
Metromix went to the first one, which was last Saturday. They're saying that it's the start of a new venue called The Ark. But I don't think that's quite right. It looks more like an event promoter renting out the space on a weekly basis -- there's no liquor license, and the only food is an occasional buffet.
I called the people who are in charge of it, but nobody has gotten back to me yet.
Still, it's another spot to dance on a regular basis. And heaven knows, Baltimore needs more of that.
