The end of the Tasty’s tenure in Harvard Square, along with other similar eateries, is considered emblematic of the chronic gentrification that started in the late 1990s.

The Tasty Sandwich Shop, a diner restaurant in Cambridge, open 24 hours a day from 1916 to 1997 at 6 John F. Kennedy Street. Behind the counter is chef Don Valcovic, on the right is Al Nidle, publisher of Street Magazine at the time. The restaurant’s customers ranged from long-time residents, students from Harvard University, to bankers and businessmen, all mixing informally.
