I'm on the Sirena now. Fifth Oceania cruise; 1st post covid. I believe the food service is as good or maybe even better than my previous experiences. I was pleasantly surprised based on some of the feedback on this forum. That said, it depends so heavily on the particular chef, crew, etc you happen to encounter on your cruise. I believe they are clearly attempting to replicate the pre-covid food experience. Providing this just as an additional data point.
