Drinks
non-alcoholic: English tea
alcoholic: bitter - many brands, oh yes and a Black and Tan when I can find bottled Guinness, Cretaceous, it's only any good with bottled Guinness
Food
homemade: hmm, roast leg of lamb with all the trimmings followed by my own apple pie or bread and butter pudding
fast food: noodle soup sitting at a street stall in Thailand, otherwise fish and chips - and the best I've ever tasted was in Esperance WA, fish caught that afternoon with perfect beer-batter
restaurant: Thai definitely now there are so many good ones in the UK
