Roti

Roti isn't a Thai dish as such — at least, not as far as I'm aware — but they've got plenty of it on the street here in Pai, and I hear that they have it elsewhere in Thailand as well. It's a very thin pancake, cooked in about 30 seconds over a hot stove (from a small handful of dough), and commonly offered with such fillings as banana, chocolate and pineapple. As well as being delicious, roti is also the perfect dessert to fill that gap in your stomach, which seems to so annoyingly form several hours after dinner. The street vendors are well aware of this magical property that their pancakes possess, and as such, they can be found flippin' and sizzlin' every night, well into the wee hours of the evening.
