Rastarant Sigiriya is your best option for some drinks in town. Sigiriya doesn't have much (or any) night life but this restaurant/bar does provide some music and cocktails that could escalate into a good vibe with the right people. They have a cute treehouse with rasta lights that gives a cozy atmosphere.

I wouldn't eat there since its way overpriced for the same food down the road. But for drinks, its a good choice!
