Each Canadian region serves up its own unique regional specialties to visitors. Quebec's best known signature dishes are tourtiere meat pies and poutine, French fries topped with gravy and cheese curd. Lobster, seafood, and curled fern heads called fiddleheads are most likely to be found on Atlantic Canadian restaurant menus, while pirogies are now a western Canadian food staple thanks to the region's sizable Ukrainian immigrant population. All Canadian cities and towns have their own recommended watering holes, but Vancouver and Montreal are two of the country's liveliest cities in terms of nightlife.
