VIDEO. More than 50 firefighters extinguished a two-alarm blaze that broke out at a mall restaurant early Wednesday. Winston-Salem crews responded to a fire just before 1:30 a.m. at the TGI Fridays at Haines Mall, according to the department. The restaurant's sprinklers were able to keep the flames contained to the kitchen area, and it took firefighters nearly an hour to get the blaze under control. No one was hurt in the fire which was caused by accumulated grease in the cooking exhaust duct work overheating, WFMY-TV reports. A helmet camera worn by one of the firefighters captured crews tackling the flames inside the restaurant.
