What's the local grog? The other thing is that Spain is not Muslim whereas Indonesia is.
I'm not sure what the state of play is on food though. If you've been to Spain maybe you can advise?
What Al said. The local grog is a traditional "palm wine" which smells a bit like petrol but won't kill you, but isn't very strong. So they add methanol to it to make it taste stronger for the tourist trade.
It don't matter how drunk I am, that sh1t tastes like a failed chemical experiment to me. It does some serious damage to tourists on a regular basis and kills a few as well. The authorities turn a blind eye (no pun intended) to the practice.
And yes, it's Indonesia. But it's Bali, and Islam didn't quite make it that far East. The dominant religions are Buddhism and Hinduism, which were the dominant religions throughout the region prior to the adoption of Islam.
Indonesian culture is traditionally very tolerant, but that is changing with more hard-line interpretations of Islam gaining ground. Some of that is being imposed on Bali, unfortunately.
In terms of food, it's not very Spanish. You can get western food or you can get Indonesian food. "Bali belly" is the common name for the food poisoning that many people come down with in Bali. Sometimes with street food the food itself is fresh and properly cooked but the plates and utensils are wiped with a filthy cloth and that is why you get sick. Bringing your own utensils or using disposable containers and utensils is always a good idea.
