Looking very nondescript in this rather old coffeeshop is the "Indo Pura Muslim Food" stall. But do not be distracted by appearance because their "ayam penyet" is a real gem.
Extreme crunch of skin plus supreme juiciness of meat is a must for any "ayam penyet" worth its salt, but making theirs extra Burpple-worthy is the chilli sambal. It's truly fragrant and lip-stingingly hot. Mix it into the fluffy white rice if you can take the spiciness. Ask the stall-owner uncle nicely and he might also throw in some extra terrible-for-you-but-terribly-delicious fried batter bits.
