The hotel is next to Patong Beach, so we went to Patong Beach's night market at night.
The night market is a combination of various food stalls, including grilled skewers, freshly squeezed juices, pancakes, etc. The things sold are no different from other night markets, but Patong has a large consumer group, so the things sold are cheaper.
For fruit, I recommend small pineapples, which are very sweet. I don't recommend durian. We went there in December, and the guide said it was the durian season, but the fruit stalls basically didn't sell it. I found one that sold it, but it didn't taste good.
