There are two places that might work.
1. This is actually a co-working space, but they are very enthusiastic about board games. Maybe u can ask them if you could host ur table top session there. https://grindtime.space/
2. The second option is actually a card game store north of phuket town where I generally go to play MTG, but they used to play some smaller DnD games there, too.
I know the owner and I am pretty sure he'd welcome u to play at his store. However, there is no aircon (just fans) and the store is a bit messy. :)

Let me know if you are interested, I could ask him directly.
