Usually a picnic means you bring the food. Ask the host what you can bring and the common reply would be the drinks for the boys which means beer or other alcoholic drinks. With the pulutan (chaser food) you can probably buy it along the way or even on the site of the picnic. If there is a grilling area the best to bring is barbecue on a stick that you can broil. Just don’t forget to bring the charcoal. It would be fun to eat on banana leaf just like a boodle fight.
