Tim Horton's isn't that great but to call it the worst isn't fair at all. Their coffee fucking sucks and they only have one god damn kind, can't even get a dark roast, yet people line up across the block to get it (at least around here). Their donuts are pretty good I think, i particularly like the apple fritters. Their chilli isn't too bad either and it's pretty cheap. As for the soup and sandwich, those also aren't too bad I mean a turkey sandwich literally only has a bun, turkey roll, bacon, lettuce and tomato and it's at least decent. Perhaps the Tim's around here are a bit better than elsewhere (no idea how that would be) but I wouldn't call them the worst by any stretch.
To me the worst sit-downs I have experienced are Boston Pizza and Montana's. It's laughable how bad Boston Pizza's food is and they also stopped showing the UFC in them here a few years ago which is the only reason to ever go. I honestly have never had a worse steak in my life than I had at Montana's and for them to have "steakhouse" on the sign in neon lights is fucking hilarious. It took them 30 minutes to give us water one time there, I mean how fucking hard is it to put tap water in a mason jar and dress it up with a slice of lemon?
