Newton North High School’s student-run restaurant will reopen this week to students during lunchtime. School officials and the district’s food contractor, Whitsons Culinary Group, agreed that the Tiger’s Loft Bistro should be allowed to serve students, despite a clause in the food services contract that barred competition. Tiger’s Loft, a long-established institution at Newton North, has been off-limits to students during lunchtime since late January, after Whitsons complained about the operation. School district officials said they are pleased that Whitsons was willing to collaborate with the students. The company is also interested in working with the culinary arts students and helping with bistro’s educational component.
