You guys need a new bartender. A good Long Island Ice Tea can go down like water. Very easy to drink too many of them.
In fact, that's part of the joke. Long Islands (when mixed correctly) really do taste suspiciously close to actual ice tea.
When I could have alcohol, LI iced teas were the only thing I'd drink--besides Shirley Temples. Polar opposites. Of course, I only liked them if I could not taste the alcohol, the "mixed correctly" part. Made right, they can be drunk quickly like regular iced tea, one after another.
