Word’s out on LTHForum that Patty’s Diner, the Reader‘s 2009 pick for Best Diner, is closing next month. Owner Patty Tunk tells Reader contributor Gary Wiviott that the bank that owns the property has raised the rent by 50 percent, an unmanageable increase for her. She’s been asked to vacate the premises by May 6, though she says there’s a slight chance of her being allowed to remain through the end of the month. Tunk has been whipping up breakfasts and lunches from scratch in the space for 20 years. Much gnashing of teeth on the part of LTHers, who named Patty’s one of its Great Neighborhood Restaurants.
