Saying goodbye to Da Cake Spott

Ever since Megan and I moved to Flatbush Avenue, this cryptic storefront sat empty across the street. Who built it? What was its purpose?
 As far as I can gather, it was rumored to be a bakery from the owner of 'Snice, but I don't think it was confirmed. The sign went up in 2007, and besides workers visiting from time to time, the place never opened.
Now it looks like a spa is opening there, and the afternoon after I took this photo, those big red letters were gone. So goodbye, Da Cake Spott, your name brought a smile to my face and bafflement to my mind every morning.
