I flew TPAC recently both ways.

Excellent inflight service both ways. As a DM, they also come first before asking others to ensure choice of first meal.

HKG-LAX there was no burger option, so I was a little disappointed, but on the return LAX-HKG it was there and similar quality to what it was before.

Generally I found that the quality of the breakfast main course served on TPAC flights has improved since pre-Covid.

HKG-LAX I asked for a hot chocolate around 5 hours before landing and they had run out. Not a big deal and I had something else instead but I'm just mentioning this as a data point.

A minor complaint, was that I was sitting towards the back of the cabin both ways (HKG-LAX was a last minute AM upgrade at check in desk and LAX-HKG was an op-up) and with the newer style of plated service, there was quite a bit of lag between those at the front getting meals vs those at the back. However, I would actually say it's more of an observation rather than a complaint even.
