Bombay Sapphire and tonic. I'm not normally one to specify a spirit at the bar or elsewhere but I feel like I have been cheated growing up around Gordon's and Gordon's only as far as gin goes. Not top-end stuff but bloody nice.
edit: or rather Gordon's is still probably ok, I just prefer this. Was at my missus' uncle's the other day and he gave me a glass of some gin he'd brought back from Majorca which was absolutely fucking lovely, and I cannot remember the name for the life of me, just know it had like a notably citrus-y taste under the usual pine needles
