My wife and I are taking a deferred honeymoon to Scotland at the end of the month and we’d both love to have a bit of a black tie night. Would it be inappropriate to wear the PC (along with her in a formal gown) to a very nice restaurant for dinner one of the nights we’re there? Not sure what formality levels are typical in Scotland. Where I live in the US, it would be a bit odd to go to even a nice restaurant in a tux. Though I suppose a bit odd is fine so long as it’s not wholly inappropriate.

Thanks in advance!

PS - Would love any recommendations for restaurants where black tie might be appropriate. Thanks!
