What's the best, most refreshing drink you've had this summer?
For me, it was a Gin-ger Tonic at Gramercy Tavern in NYC. Tanqueray gin, "ginger essence," lime, and tonic, garnished with crystallized ginger. No sugar. It was very gingery and very refreshing, and a great pre-dinner drink because it really piqued the appetite.
On the non-alcoholic side, on a hot day, some homemade watermelon lemonade really hit the spot.
