Not at all - a happy wife makes a happy life - and if you only sail once every few years make it memorable. As for specialty restaurants, Giovanni's is always one of our favorites, and we could eat there every night. Between the Chops and Gio's menus, you could easily eat in those two every night and never have the same meal twice.
The drink package on the other hand is not something we would do (Neither one of us could ever drink enough to break even at $65/pp/per day). If your wife is not a drinker, check and see if you can get the refreshment package instead.
Just to add: if you are in a full suite (GS or above) you can also order room service for any meal from breakfast to dinner from the MDR menu at no charge.
