Quebec City does not have the same deep Italian-deli sandwich culture as Montreal or some North American cities, but there are still a few places to look when you want a substantial Italian-style sandwich.
Casa Panatoni
Casa Panatoni in Cap-Rouge remains a current option for sandwiches and pizza. Its submarines are part of the reason locals have recommended it for years.
Franky Johnny
Franky Johnny on rue Saint-Vallier Ouest is a sandwich-focused shop rather than a traditional Italian grocery. It is a good choice if what you really want is a creative, generously built sandwich.
Comptoir La Piadina
Comptoir La Piadina in Sainte-Foy specializes in Italian food and piadina-style sandwiches. It is a stronger fit if your idea of an Italian sandwich includes the thin flatbread associated with Emilia-Romagna rather than an Italian-American deli sub.
What about an old-school Italian deli?
That specific format is less common in Quebec City. If you want to build your own sandwich, European and Italian groceries can be a better bet for cured meats, cheese and bread than searching only for sandwich counters.
