On the way from Denpasar to Ubud I used to stop for a lunch at local eatery called Lembongan. Only fresh fish and fish soup is served there.
My favorite restaurant in Vientiane is called Via Via. I love the good selection of wines there and all food coming from a pizza oven. Last time I ordered a lahmacun, which was truly delicious.
Are you addicted to eat injera ? When travelling in Ethiopia, I have to eat the spongy bread every morning and evening. Injera and fresh roasted coffee are the best. You get it even in the smallest village.
