Agree with Jerremy that the evening lounge spread was probably one of the most impressive I’ve ever seen and if this wasn’t Bangkok could definitely be a meal replacement. Loved it mostly because of the sheer variety of healthy options rather than it being mostly fried things - about 10 different kinds of roasted vegetables, sun dried tomatoes, nuts, fruits, etc.
Breakfast was less spectacular (certainly a big step down from, say, having access to the full restaurant breakfast at The Athenee) but is still very good for a lounge.
