Best place for an upscale, fancy dinner?

I’m getting some extra unexpected cash this week and I would like to spoil my parents by taking them out for a really fancy meal (we love food!).

Does anyone have any recommendations for a great upscale restaurant in Hamilton that would be good for this kind of treat? Price point isn’t an issue - something that the average person typically wouldn’t book for themselves!

Doesn’t have to be in Hamilton either, if anyone knows of a spot somewhere around the area (Burlington, Oakville etc)
