This busy restaurant sits on Rue Saint-Paul, a street in Lower Town that’s lined with antique shops, hence the name. Buffet de L’Antiquaire is a classic diner—but with a Québecois twist—that has been a mainstay of the city’s dining scene for more than 40 years. The reasonably priced menu lists traditional dishes like boudin (blood sausage) and pork stew among the entrées and sugar pie and crepes among the desserts. (You can also order more typical diner fare, from burgers to omelettes.) It is open early to late, from 6 a.m. to 10 p.m. seven days a week, adding to its popularity.
