My #1 favorite is a French 75, in a quart jar.
Buzz kill - I heard some bad news about my other favorites just today:
Large margarita = 600 cal = 4 sugar donuts
Pina colada = 980 cal = 6 battered chicken wings. fried
Apple martini = 344 cal = 1 pc of German Chocolate cake
and my standby summer beverage:
Long Island Iced Tea = 1043 cal = a large platter of onion rings
I heard this on TV so I can't swear to the accuracy of the 'buzz kill' info.
