One of my top 3 eats EVER, Martin Picard's Cabane à sucre au PDC is amazing (and only 57$ per person for the meal!!!). Be ready to be seated in tight quarters with a lot of people you may not know - unless you're going with a very large group. Make sure your stomach is ready for a succulent 11-12, 4 course menu, but don't worry if you can't eat it all, the waiter will be pleased to provide you with as many take-home containers as needed!
**It should be noted that I sent in my reservation request on the morning that they opened online reservations and only heard back 3 months later. So if you're worried that you won't get in, there is hope yet!
