Would have to be 7n7. Beside being the only drink I know named after an aircraft, (a prototype anyway) it's very smooth and crisp and tastes great. ('cept in Canada, I have to get VOn7 because Seagram 7 is not available in Canada. Haven't a clue why. Seagrams is a Canadian company???)
I used to be a hard core Coke drinker, but while going through my divorce, and on anti-depressants, I started drinking Diet Pepsi and have been ever since. Regular colas now taste just way too sweet.
I love Starbucks Caramel Machiatto on a cold winter's day. Otherwise it's Starbucks Espresso Frappicino when it's warm. I do prefer Seattle's best over Starbucks, but that's not available here in Pa. Besides, Starbucks East Cost Roasting and Distribution Plant is right across the street from my office, so I'm supporting the local economy!
My glass is neither 1/2 empty nor 1/2 full, rather, the glass itself is twice as big as it should be.
