About the joint
Milestones is owned by Cara Foods. Cara Foods owns and operates several other franchises in Canada. Most relevant to the derbist is Harveys (blech) but, of course, they also run Swiss Chalet (meh) and Kelsey's (ew). So, one would expect Milestones to be equally subpar; large scale food service shlock. However, Milestones has managed, somehow, to continue to serve decent food, in a completely tolerable atmosphere! Who knew.
Of course, restaurants with big, diverse menus usually can't get anything right, and often toss a burg or two into the mix cause, after all, if someone can't find something they want a burger will do... and how hard is that to mess up? Turns, out, not hard at all. But again, Milestones has defied the odds, offering up perfectly respectable burgs.
