My favourite cocktail ever was a Sea Breeze (cranberry, grapefruit and vodka)
DS had moved to America, and it was our first visit to him in Virginia after nearly a year. He took us to New York for the weekend and as soon as we got to our hotel in mid-town Manhattan, he and MrA announced that they were off up the Empire State Building.
I was so entranced with New York I announced I was not going anywhere till I had had a cocktail in the hotel bar.
We then went up the Empire State Building and got to the top just as dusk was falling, and stayed there watching the sky turn from pink to dark blue and the city light up. Unforgettable.
