I've heard through reliable sources that Sun Valley is closing it's Danforth doors come end of July 2012.
I can't say I'm really shocked by this because the last few times I've been in for emergency or last minute items - the place was a ghost town. It's a far cry from what it was when I first moved to the 'hood close to 20 years ago. It's a shame. They seemed to loose interest, and then customers.
All in all though, I will miss them and sorry to see them pack it in.
