My husband and I stayed at an amazing hotel (The Whitelaw Hotel) in South Beach Miami, Florida. When we got to the hotel, we were so hot and they offered us some water. I swear it was the best water that I have ever had! Very easy and very refreshing, I still serve this on hot days here in the Canadian prairies. There are no real rules to this - it's all about the combination of water and cucumber. Enjoy!
