This from Eric Haak:

This came in just before 0700 hrs on Saturday morning.  Companies were given an address on the 8200 block of Cottage Grove and 8200 Maryland as well.  The first company on-scene reported that it was on Cottage Grove and that there was smoke showing from the roof.  It looked real impressive coming down Cottage Grove from the North but turned out to be just a grease chute for the jerk chicken place.
