Imagining a tourist on vacation amazed by all the unique foods they can try for the first time, making sure they have breakfast, lunch and dinner along with several snacks to try absolutely everything. Ordering full meals at least three times a day with all the sides to not miss out on a single thing!
Hitting the point every day where they feel just too full to keep going, their abdomen straining agsinst their shirt and pants button fighting to stay closed, but its a once in a lifetime experience! They certainly won't get to try it again, so they finish this meal. Then the next. Then when walking just to find something else they HAVE to try! Following their nose from place to place.
Of course they can't forget about desserts, some sweet, some savory, trying them all right before seeing an ice cream shop with flavors they've never seen before. Of course they need to test these flavors out! Maybe they'll have a new favorite to make at home.
And if their clothes get a little tight its the perfect chance to buy some clothing keepsakes, just in a size or two larger than the ones they have at home. Larger touristy shirts which should be loose but are just tight along their belly.
Just to travel to another town or city or state or country with different variations (or even the same location but trying different locations with the same foods), just to do the same thing all over again until its time to go home. Maybe learning to make some of the delicious dishes they tried, maybe planning another trip to try out new foods. All while carrying an even larger appetite with them.
