Montreal/Quebec City Minimoon

Hi everyone! My fiancé and I had plans to go to Europe for our honeymoon, but due to Covid we have decided to postpone and instead are going to take a “minimoon” after our wedding. We will be visiting Burlington, VT, Montreal, and Quebec City. This will be both of our first times in these cities, so if anyone has visited and has any recommendations of must see/must do things we would love to hear! We are big foodies, so restaurant recommendations would be great. Thanks!
