I've taken a lot of classes at BDC and I'm sad to see this happen. The building management has really taken to harrassing the owners of the studio, and in turn the students...there was a failed attempt back in September to make everyone show an ID at the door which would delay check-ins and basically make a huge headache, and I'm SURE the class rates are going to go up soon - at $18 for a single class, they're already astronomical. BDC does take up a lot of space in prime territory (several floors in a large building on Columbus Circle) and unfortunately I'm not surprised at all that the management is trying to harrass them out of the place. The real estate market in NYC is just out of control, and places like BDC and other dance studios really suffer because they are not nearly as profitable as the building managers would like. (Many other studios, like Dancespace - where I now take classes - are housed in totally decrepit buildings with paint peeling off the walls/ceilings and whatnot.)
For a city that supposedly has such a vibrant arts scene, New York is a really hostile environment for dance studios. It's sad.
