Looks like you and your sweet tooth enjoyed eating your way around Thailand. When you make it Japan, you'll be right at home. Endless array of foods and sweets to sink your teeth into. And Coco Ichiban is just the tip of the curry iceberg (no disrespect intended).
And by the way, about your secret technique to stay slim despite eating tons of ice cream without needing the gym... is the answer happiness and good mental health? I too eat and drink whatever whenever and don't put on weight. I guess we're lucky.
