Judy's on North closed 'until further notice' after early morning fire

MILWAUKEE (CBS 58) -- An east side Milwaukee restaurant is closed Tuesday because of an early morning fire. 

Judy's on North is on the first floor of a building at Prospect and North. 

Firefighters say the flames were confined to that first floor and they haven't figured out yet how the fire started. 

A post on Judy's Facebook page says there was no one in the restaurant at the time, no one was hurt, but the post says the restaurant will be closed until further notice.
