5. TEQUILA/MEZCAL
Get this instead: Paloma
Let's face it, margaritas are overrated. And if ever you find yourself in a place where they're served frozen from a machine, promptly leave. Anyway, this one's traditionally got tequila or mezcal (two fingers generally) in a highball or collins, and is then filled up with either grapefruit soda or fresh grapefruit juice (in which case club soda would be added for effervescence). Simple, and delightfully so. Some argue that it should include sugar, or even be rimmed with salt, but we can chalk that up to a matter of taste.
