Brunch at the Old Mill has 2 lots made by SimGuruKitty that can be downloaded into your game.
The Old Mill

And Stoney Falls Near the Old Mill
https://www.thesims3.com/assetDetail.html?assetId=8314505
And the Sea Shanty is an actual lot that you can place on an empty lot.
Hope this helps...?
Edit to say that SimGuruKitty has put in the address/location of the original lots in Sunset Valley that she used for the Old Brunch builds.
And also Karritz has a thread with a list of bakery builds from other Sims 3 players...?
