Coron is an off-the-beaten path destination. Do not expect to find fast food chains or big disco bars here. You do have a good offer of places to eat, though. Most of them are restaurants and bars run by expats. You will find them along the town's main road. At the end of this road there is a local market with convenience stores and some local restaurants.
There is not much night life in Coron either. Most of your night action will consist of sipping a beer, and chatting with fellow divers about your day's adventures. After the bar you can go to one of the two local discos.
