We plan to take the train from Montreal to Quebec City and return the same day next Thursday. What are the must dos that we can realistically fit in in our 7 hours? We are fine with walking the whole time, or taking public transport if needed. It looks like our starting point will be the VIA station at 450 rue de la Gare du Palais. Also, would love some recommendations on places to eat during our day. We are open to anything. Thanks!
