Workdays in it tends to be either black or green tea. I enjoy a variety of quality teas including Korean Poseong green and barley teas, Chinese oolong and longjing and of course the traditional English Breakfast and Darjeeling.
On weekends, this might be supplemented by some juice and the tea maybe replaced by an espresso macchiato (made the old fashioned way). On rare occasions if brunching out, and in company of friends, maybe also a Bloody Mary. Not so much into champagne based drinks intogether.
When flying, a tea and tomato juice combo has been the usual order. Not that I like plane breakfasts much anyway, normally try to get an Asian (Indian) vegetarian brekkie if possible.
