The Golden West flour mill just south of downtown by the viaduct? It burnt down in 2009
The mill part of the building was demolished due to extensive structural damage, but the silos were left with vague plans for some sort of creative re-use.
I visited in 2008 and got a few photos, this is the only one I can find right off.
