Poisons: Mojitos and caipirinhas

Caipirinha at Grand Cru

Ingredients: Cachaça (ca-sha-sa), sugarcane syrup and crushed limes

Damage: $8

Skinny: Order just one of these strong drinks at Grand Cru, and, trust us, you're set for the night. This drink, while refreshing, was incredibly strong. The alcohol content of cachaça can vary from 38 percent to as much as 80 percent by volume. Clearly, Grand Cru uses the high-octane stuff.
