The first part of a long-awaited collaboration between Cumbrae’s butchers and the Terroni restaurant group is set to open Saturday at 8 a.m. at the former Postal Station K development at Yonge St. and Mongomery Ave. The site is now known as Montgomery Square. A first-floor grocery store including a pastry and bake area will welcome shoppers first thing in the morning. It’s recorded at the Stock TC Instagram account that a second-floor restaurant and bar will open in the fall. It will feature a third-floor patio. The origin of the chosen name for this venture — Stock TC — remains murky but it appears to be a play on the names Terroni, Cumbrae and Terroni’s restaurant division, Sud Forno. We’ll let you know.
