As its name suggests, Wilensky's is a lunch counter--one that's only open until 4:00, weekdays and Saturdays. It's now celebrating its 80th anniversary (going on 81), and with few exceptions it looks like its been preserved in amber since the '40s.
One of Montreal's few truly great sandwiches, and a certified original, the Wilensky Special is still priced under $5. So what if it's simply a pressed hot bologna and salami sandwich with mustard? Some days nothing else comes close. I recommend ordering yours with Kraft cheese and a side order of half-sours to get the full experience. And don't forget to order a fountain drink.
An institution (sometimes in more than one sense), and not just because of The Apprenticeship of Duddy Kravitz. Beware of imitators--this is the real deal.
