I had some dinner yesterday in T3 Flounge at around 17.35.
The buffet immediately after they brought it out was awesome. Really, really good. And I had already eaten myself decently full at the CX Flounge (fruits, satay and wonton noodle soup.... all were great also) so it can't be the hunger.
I had the lovely crisp pork belly, vegetable curry and thai chicken something. My friend had the mushroom pasta. We thought the food was amazing.
Don't know about the hygiene, but I feel fine.
