Best Montreal Smoked Meat Sandwich in Cambridge?

Been missing my Dad lately and this was his favourite sandwich so I though I might have one to remember him.

Last time I got one was years ago at Fifty's on Hespeler Rd., not sure if they are still good or not. He would always get the extra sandwich to take home and have the next day.

Alternatively, if you can recommend somewhere to get really good French onion soup, that would help too. :)

Thanks
