Plainly speaking, I like my pratas anything but plain.
Tried an egg one ($2.50) at "Cafe O" yesterday and found it really quite satisfactory.
Overall, it's fluffy as the layers of folded dough didn't clump together in a dead heap, and also lightly flaky and crisp in parts - a combo which is incidentally, my preferred texture for pratas. Size-wise, it's bigger than average. Instead of the usual dhal, or mutton and fish curry, this came with a thick-in-a-slightly-starchy-way chicken curry gravy.
