My non-alcoholic drink is always tomato juice, especially in the morning. There is just something about it. On side note, tomato juice with a Denver omelet with cheese is perhaps my favorite breakfast. I am afraid to drink water or coffee en route. I have seen far to many people get sick.
My alcoholic drink of choice is Sapphire gin with a slice of lime and one ice cube (to much ice is terrible for your drink). On the ground my drink of choice is a Sapphire martini with 2 blue cheese olives. (The blue cheese olives are fantastic when they soak in the gin and vermouth)
