Best memorable restaurant for 15+ people

[RobinBaby]

Hi all,

I'm heading to Quebec City at the end of July for a reunion with 15 or so others, including children. I've never been before and curious about:

1) A restaurant that would be a great experience for everyone - good food, atmosphere, not sky-high prices.

2) a romantic restaurant for 2 with memorable food that is unique to the city.

Thanks in advance!
Andrea
