I found myself standing in front of many a street food stall holding one finger up and smiling. It seems to work, but if you want to call some of these things by their names, this might help!
Coconut Roasties (available at the Night Market by Super English) – ka-nom krok
Deep-Fried Dough (a breakfast favorite) – bah-torng-goh
Steamed Buns (cross the bridge heading north, make your first right, stop at the lady just a bit up on the left. just do it.) – sah-lah-bow
Mixed Nuts (protein on the go!) – gai sahm yahng
If you’re eating something you like, say “a-roy mahk.” It means “That was delicious!”
