If you’re familiar with the book, I’m mainly just looking to fill in the gaps that the book doesn’t really cover.
For example, I’m aware of the different orders (like Doric, Tuscan, Ionic, Corinthian, and composite) but I don’t know if the orders are only used to describe the pillars (I wouldn’t be surprised if there’s a more accurate name for them) or if they extend to other parts.
Another example would be what kinds of foods would be customarily made and would the types of food eaten in a poor home versus a wealthy home versus a tavern/inn differ from each other.
Final example would be if there’s aqueduct systems in the poleis (and drainage) and how would they work?
Edit: I don’t know how to change the flair. (I’m on mobile.)
Not to discourage any further answers, but /u/Iphikrates' satisfying answer on the Athenian diet in the 4th Century BC really fed my curiosity.
There are numerous other answers that will help you get a slice of life in ancient Greece in FAQ on the Hellenic Mediterranean. You can also check out r/AskHistorians' Recommended Reading List on Ancient Greece](https://www.reddit.com/r/AskHistorians/wiki/books/europe#wiki_ancient_greece), there are some great history books in there that night be helpful to you.
In particular, Iphikrates highly recommended Courtesans and Fishcakes by James Davidson. Having read it myself on his recommendation, I think it would be every bit as interesting to you as it was to me. Since you are specifically looking for a guidebook to fact check worldbuilding elements, a broad overview of Ancient Athens sounds like a great reference for you.
As an aside, you might get more answers (and answers of greater depth and quality) if you post individual questions rather than casting too wide a net with a multi-question post.
Happy worldbuilding!
