Toronto's newest banh mi restaurant is the definition of a hidden gem: it's literally tucked inside a neighbourhood convenience store. Sandwich shops in Toronto are a dime a dozen, and that number only seems to grow by the day. In the case of Leslieville's so-new-it's-only-soft-opened Oi Banh Mi, the quality that helps it stand out is also what keeps it hidden: the sandwich shop operates out of a window attached to a Queen East convenience store. According to the sandwich shop's Instagram bio, it's "Toronto's first Banh Mi walk-up window experience," and, as far as I'm aware, they've got a pretty legitimate claim to that title. Oi Banh Mi is located at 900 Queen St. E.
