Lemon-lime Soda

Probably the most used soft drink. (A bartender secret: Whenever someone asks for a "good drink", there is a way to always succeed: In a long drink glass, filled with ice, pour one part vodka, one part fruit liqueur (strawberry for instance), a dash of lime- or lemon juice, and fill with lemon-lime soda. Garnish, serve with two straws. Success!)
