Look, first of all, if you're not drinking single malt scotch, you're drinking crap.
Secondly, as long as it's before noon, Manhattans are always appropriate.
After lunch, for a little zing, I would say Vodka Stingers are a nice treat. Ofc, Drambuie Stingers are great any time you feel sexy.
Lastly, if you're a classy dude like me, you always greet the day with a bottle of vintage champagne. It lends a sparkle to the day.
