At brothers David, Philip, and Peter Chau’s North York Banh Mi Boys outpost, they’re slinging fancy Vietnamese submarines made on crusty baguettes. Sandwich fillings include duck confit and squid, alongside classic toppings such as grilled pork. The menu is not strictly updated Vietnamese, though. A Korean take on poutine (which piles kimchi, mayo, and pulled pork on top of fries) is a favorite with the voracious student crowd that frequents this sandwich shop.
