I found this one on the cocktail menu at Morton's Steakhouse and started making it myself- I haven't had a single person tell me anything except "this is absolutely delicious". It really is a perfect summer drink.

In a large rocks glass, muddle 3 slices of seedless cucumber. Add:

1.5 oz vodka (Morton's uses Absolut 100, and maybe a little less than 1.5 oz)
.5 oz St. Germain Elderflower Liqueur
splash of fresh lime juice
top with ginger ale (Reeds, Stewarts, or another high-end brand is best but Canada Dry will work).

stir gently and enjoy.

Oops, wrong link above for the recipe, but now you know where to buy Bitter Lemon, also very good with Pimms Cup.
Here is another Pimm's Cup recipe:

Don't forget the Mojito! To make it easier, I steep mint in water with sugar and lime (a minty lime simple syrup ) and then pour rum in a tall glass, add minty syrup and top with club soda. After straining the mint out , the syrup is clean and easier to drink with no bits of mint getting stuck on your tongue. To really cheat, buy some "Simply Limeade" and steep mint in it!
so refreshing and tasty.

I had forgotten about a Gin Rickey and cannot wait to try one again! thanks!
