Those nongshim shrimp crackers are everywhere down here, there used to be this super specific flavour my ex has been chasing down for years now, no luck.
I had these bhut jolokia chips once and they were pretty damn tasty, but the quality of each bag was very inconsistent so I stopped buying them, some would be hot, which I love while others would be weak as piss and they're not exactly common either so it's pretty disappointing.
Habanero and Jalapeño get my vote, had Jalapeño & Cheese Pringles recently those were tip top
