I was dragged to the tower for a business dinner a couple years ago and was pleasantly surprised at the food. I was expecting tourist trap crud ($15 dollar frozen patty hamburgers and the like) and it definitely wasn't that, it was decent high end restaurant/hotel dining room food. The main problem was that it was overpriced. Not a foodie destination restaurant but OK.

If your spouse has a thing for revolving restaurants there is another one in Toronto on top of the Westin Harbour Castle hotel and there are two of them in Niagara Falls (although I can't vouch in any way for the food in either)
