This community is small, its not productive to give people shit for posting decent quality pictures of food, regardless of your hangups about what you want the community to be. There’ll be more room for being picky about what posts belong on a given community when lemmy is big enough there are plenty of healthy communities for food related posts.
I can understand complaints about how eatable the dish is, or about the pretentious plating, but we can communicate those sentiments better than this, and ultimately no one has to like any given post that shows up here. If you want post quality to be better its probably more productive to post content you think is deserving of the community name
