Along those lines, Dagon Fel would have the same citrus and seafood, but they might have a trade established with Solthsheim (probably through Khuul) to bring in bear and wolf meat and possibly other foods which are more like what was available to them in Skyrim.
I realize some of this might not even be possible or practical to implement and without explanation, it may seem odd to the average player, but a few lines in the book pertaining to the foods would be all the explanation needed. After all, sailors have always been a source of the new and interesting and they generally keep a supply of what they like, regardless of whether or not it's popular.
Um, I don't know if this has been addressed, but the restaurant, "Food of the Gods", although beautiful, doesn't really seem to serve any purpose to the mod or the game. Is there a way to separate it out into a standalone esp? The changes in the landscape really mess with my distant land and animated grass.
