It would either be Tandoori chicken, this was my first ever taste of Indian food when I was about 19 and my taste buds were very under developed. I remember thinking at the time "how did I manage to live without ever having tasted this". I have moved on to more interesting things on an Indian menu, but still like to come back to Tandoori chicken from time to time. If I couldn't have that I'd have one of those pasta dishes you can only get in Italy where there are about three ingredients, very simple, but nevertheless manage to taste sublime and somehow you know you could never recreate it and make it taste as good at home. For desert, like grannyactivist, I'd evoke a childhood memory,my nana's steamed jam pudding. Or chocolate profiteroles a la 1970s as sold by the Spaghetti House chains in London. I have never tasted any quite like them since they were very big with milk chocolate sauce, now they are all quite small with a dark chocolate sauce, just not the same.
