The food is good. The price a bit above average. I've stopped ordering from there after my order was screwed up on many occasion or just arriving very late.
So if you order out from there, ensure to check your order before the delivery man leave and order ahead of time.
Otherwise, nice restaurant for delivery.
Stayed there twice. Both times on the 3rd floor.
Not a modern setup by any stretch but the personnel is very friendly, the rates are very affordable and the convention center is worth it. As for the breakfast, it's hotel quality breakfast but the service is impeccable.
If I need to stay in Trois-Rivière again, I would definitely choose the Delta again.
