If things don't change will try this one out on Wednesday night since I have till middle Friday to recuperate. If the bar you go doesn't carry Cointreau as in other drinks I have found that Triple Sec would as well since they are made from orange peels and rhinds. Now the lemon juice could make it sour but thats the whole beauty of trying new drinks out. And besides try to keep a straight face when ordering this drink when you buy it for a friend so he doesn't know your setting him up.
