Yep, part of travel is to try new things.
I make it a practice to dine out at least 1 day a week and switch doing so for supper and for lunch. I try to go where things local are the menu vs. going to chain sites.
Re. what you will be asked to throw out: yep, see stickies. But some principals: that which will keep or attract insects, ie. root vegetables, citrus fruit.
& yes roadside stands & or farmers' markets beat all chain groceries by the mile for freshness, taste and selection.
NO firewood for the same reason.
Pet food in original containers. & times may happen when you will not be allowed to bring that too. Best to have your pets on a brand you can buy in most stores. If need be, call stores in town where you will cross.
