I can confirm the genuine excellence of Waroeng in Somersworth. This is beter than any Indonesian restaurant in NYC. Rejoice!
The place is humble but clean, with food ordered at the counter and served on disposable plates. This is clearly a Christian family place (see the wall hangings and electronic message on the register), and the staff was smiley and helpful.
I had a bowl of their fish cakes in a sweet and sour vinegar broth and it was both unusual and soulfully satisfying. Its one of those dishes that you wonder how you lived without it in your stable of favorites. My wife had a jackfruit dish, which has the texture and integral sweetness of the most tender pulled pork. It came with a small portion of succulent curried meat on the bone and some potato-like vegetable in a coconut based sauce.
In addition of a case of boxed teas and soft drink, they make ice drinks. One is a combination of chunks of avocado, coconut, jello cubes, and rosewater I think. Another is made with ice and cantaloupe, but the woman behind the counter discouraged us from that one. They also had something that I could make out as a durian drink on the untranslated specials menu. We took home a box of their rum custard cream puffs, and next time we'll try the crescent-shaped chocolate pastries. They also have a few pre-packaged dishes in the cooler, such as cut tropical fruits with a serving of their sauce.
It is on the left side of the main drag in Somersworth just as you are leaving Dover.
