The Kota Kinabalu Plaza Premium Lounge is of a decent-sized, and offers food cooked to order. I probably wouldn’t pay for it, but it’s an average international lounge, and was pretty empty when I visited.
The space is pretty large, and is divided into the dining area, and the lounging area. There are monitors displaying flight information scattered around the lounge.
While the buffet available is rather unappetizing, they do have cooked-to-order food options. When I was there, I was interested in the black pepper chicken, but they were out of that. They only had the pasta option, which I had zero interest in, so I didn’t get anything to eat in the lounge.
They do have sodas and other beverages in the fridge for self service. I did go to the bathroom, and it was clean. One source of annoyance? While the place is outfitted with USB chargers at the base of their lamps, it seems like none of them worked!
