My favorite thing to do in a new country?

Go to the local grocery store.

Wander the snack aisle and try every new chip flavor I can find.

Explore the spice section, and see what I can add to my collection at home

Pick up weird cola/soda flavors.

In Amsterdam, it was FEBO snack walls and flaky sausage rolls from the train station.

In Thailand, it was 7-Eleven meals I still think about.
