Poisons: Super-sized drinks

Oversized margaritas at Mex

Ingredients: Varies depending on the type of margarita

Damage: $15 for 42 ounces, $35 for 120 ounces

Skinny: OK, we're not kidding when we say that the 42-ounce margarita at Mex is not the largest size. Also available is a 120-ounce tower of margarita that we're fairly sure is meant to act as a behind-the-bar dispenser, not a drink served to customers. Either size comes in a variety of flavors, from the standard marg to strawberry or raspberry varieties. We tried the strawberry margarita and found it sugary but tasty. It hardly seemed as if we'd sucked down 42 ounces of booze.

Price per ounce: $0.36 per ounce (the price drops to $0.29 per ounce, if you spring for the 120-ounce tower)
