I tend to go by the local geography. You'll find wild oats and venison on the menu in the foothills, peaches in places with cold winters and pears in the places without, that kind of thing. A lot more small animals than large ones, and a lot more grains and vegetables than meat.
If you or one of your close (within walking distance) neighbors had to grow or raise every bit of food you ever see, what would be on the menu for Thanksgiving at your house? I'm on the Gulf Coast, blueberries would be a luxury item because it's hard to make them do well down here, but I can get you all the blackberries you want, they grow wild everywhere.
If someone has to put it on a wagon, and bring it for miles over bad roads in a wagon with poor springs at 2 or 3 MPH, you either aren't gonna see it at all or it's going to be hellishly expensive.
Also, beer and wine tend to not travel well, so most spirits will be locally brewed/vinted/distilled. No peach brandy in the tropics, no orange liqueurs in the frozen north.
