In no way was this meal at Delly Boys groundbreaking or monumental. I wasn't around 50 years ago when the place opened, but I can almost guarantee you that the menu probably hasn't changed munch. Granted, less deli-like items have been added to the menu through the years I can assume - pizza, pastas, and six different kinds of poutine.
Delly boys isn't trying to be something it's not, because it isn't anything other than a deli - one that's been around for nearly 50 years - they're serving what people want, and the people want what they serve.
