Closed: SweetSpot Baker's Workshop

This weekend my husband and I were at the Irvine Spectrum and noticed that SweetSpot Baker's Workshop is gone. To be honest, I was actually surprised it lasted as long as it did. They had a fun concept idea (I wrote about it back in 2008), but I just didn't see too much potential for it at the Spectrum. SweetSpot replaced Sweet Lorraine's, another failed cupcake shop, so I wonder what will be the next replacement?
