The newsdesk can be a lonely place at 4:30 in the morning. Other than security guards and cleaners, pretty much your only conversations are by telephone with fire and police to check-in on overnight events. This morning I made my usual call to the fire department, only to be told that they were at that very moment responding to a fire just two blocks east of our studio. The popular 73 North restaurant on Sparks Street near Metcalfe was on fire. So what better way to report on a morning story than to trot over with a small portable camera and cover the scene. Here's some of the action. The details: officials say the fire started in the kitchen; damage estimated at $100,000.
